Prankster Comet
Prankster Comets are celestial beings that occasionally descend upon a galaxy during the course of Super Mario Galaxy and Super Mario Galaxy 2. While they are within the galaxy's orbit, a new challenge to obtain a Power Star will be presented. A previous mission is often used, but with an added criteria.
Super Mario Galaxy[edit]
In the first game, each of the main fifteen galaxies will present two comet challenges, one being specific to the level and the other being a Purple Comet. Their positions can be tracked on any of the maps found in the Comet Observatory. While a Prankster Comet is in orbit, no other missions can be played on the galaxy in question. Prankster Comets will disappear if a Power Star is obtained from a different mission, and will reappear again if another is obtained. In addition, a Luma near the Terrace in the Comet Observatory will offer to move a comet for 20 Star Bits.
There are five kinds of Prankster Comets in total, as listed below:
Speedy Comet[edit]
The Speedy Comet is a red comet that challenges Mario to finish a previous mission within a time limit. If Mario runs out of time, he loses a life. Losing a life at any time during a Speedy Comet challenge will require Mario to start over from the beginning, despite any checkpoints he would have passed in the normal mission.
The galaxies that play host to the Speedy Comet are:
- Good Egg Galaxy - Dino Piranha Speed Run
- Space Junk Galaxy - Pull Star Speed Run
- Dusty Dune Galaxy - Sand Blast Speed Run
- Dreadnought Galaxy - Topman Tribe Speed Run
Cosmic Comet[edit]
The Cosmic Comet is a blue comet that triggers the creation of Cosmic Mario. Mario must race Cosmic Mario through a portion of the galaxy to reach a Power Star. If Cosmic Mario gets to the Power Star first, Mario will lose a life.
The galaxies that play host to the Cosmic Comet are:
- Honeyhive Galaxy - Honeyhive Cosmic Mario Race
- Freezeflame Galaxy - Frosty Cosmic Mario Race
- Gold Leaf Galaxy - Cosmic Mario Forest Race
- Sea Slide Galaxy - Underwater Cosmic Mario Race
Daredevil Comet[edit]
The Daredevil Comet is a silver comet that reduces Mario's health to one and challenges him to complete a mission without taking damage. It most often appears in conjunction with a boss fight, with the comet carrying Mario directly to the battle arena. The only exception is in the Melty Molten Galaxy, where Mario must complete the entire mission or be forced to restart from the beginning.
The galaxies that play host to the Daredevil Comet are:
- Battledome Galaxy - Topmaniac's Daredevil Run
- Ghostly Galaxy - Bouldergeist's Daredevil Run
- Gusty Garden Galaxy - Major Burrows's Daredevil Run
- Deep Dark Galaxy - Daredevil Run to the Ghost Ship
- Melty Molten Galaxy - Lava Spire Daredevil Run
Fast Foes Comet[edit]
The Fast Foes Comet is a yellow comet that causes enemies to travel faster in the galaxy where the comet passes by. In both instances of its passing, these enemies consist of Thwomps (regular and box-shaped) and spiked panels. Because Thwomps will instantly kill Mario if they crush him, these missions become somewhat more dangerous; however, Mario will always start close to the Power Star rather than at the beginning of the level.
The galaxies that play host to the Fast Foes Comet are:
- Beach Bowl Galaxy - Fast Foes on the Cyclone Stone
- Toy Time Galaxy - Fast Foes of Toy Time
Purple Comet[edit]
The Purple Comet is a special comet that appears after clearing Bowser's Galaxy Reactor. Unlike other Prankster Comets, it appears in all fifteen of the major galaxies. In all of these challenges, Mario must collect 100 Purple Coins without dying to make a Power Star appear. However, some galaxies have their own special conditions applied, including time limits or limited chances to get each coin.
The following galaxies have no special conditions, and only require Mario to collect every coin:
- Good Egg Galaxy - Purple Coin Omelet
- Honeyhive Galaxy - The Honeyhive's Purple Coins
- Beach Bowl Galaxy - Beachcombing for Purple Coins
- Freezeflame Galaxy - Purple Coins on the Summit
- Dusty Dune Galaxy - Purple Coins in the Desert
- Sea Slide Galaxy - Purple Coins by the Seaside
- Deep Dark Galaxy - Plunder the Purple Coins
- Melty Molten Galaxy - Red-Hot Purple Coins
The following galaxies employ a time limit during Purple Comet missions; most have 150 coins instead of 100, except for the Space Junk Galaxy and Gold Leaf Galaxy:
- Space Junk Galaxy - Purple Coin Spacewalk
- Ghostly Galaxy - Purple Coins in the Bone Pen
- Gusty Garden Galaxy - Purple Coins on the Puzzle Cube
- Gold Leaf Galaxy - Purple Coins in the Woods
- Toy Time Galaxy - Luigi's Purple Coins
The following galaxies will force Mario to ride a platform throughout the level, giving him only one chance to get every coin; if he misses any, the Gearmo at the end of the level criticizes his performance and takes a life:
- Battlerock Galaxy - Purple Coins on the Battlerock
- Dreadnought Galaxy - Battlestation's Purple Coins
In addition to these, the Gateway Galaxy offers a Purple Coin challenge as soon as it can be returned to, and does not require the Purple Comet to be in orbit. After meeting with Rosalina for the second time, a red Luma will appear and challenge Mario to collect 100 Purple Coins while using the Red Star power-up. If Mario does so, he earns a special red Power Star and the ability to use the Red Star in the Comet Observatory.
Another Purple Coin challenge can be found after 120 Power Stars have been collected by both Mario and Luigi. When this has been done, the Grand Finale Galaxy can be accessed by either brother. Collecting the 100 Purple Coins here will earn them a 121st star.
Super Mario Galaxy 2[edit]
All Prankster Comets appear yellow in the sequel and are no longer named, though Speed Run, Daredevil Run, and Purple Coin missions return from the previous game. Romp, Cosmic Clone, and Double Time missions are introduced alongside these. Some comets may also extend the length of a level or replace existing sections with new ones.
In Super Mario Galaxy 2, Comet Medals must be collected within the galaxies before Prankster Comets will appear (which still will not happen until the player has reached World 3). The first level of every galaxy will have a Comet Medal hidden in it. Despite this, not every galaxy will have a comet appear over it. Also of note is that, even with every Comet Medal collected, the Prankster Comet for Grandmaster Galaxy will not appear until 9999 Star Bits have also been deposited with the Banktoad.
The galaxies that don't have comets include:
- Fluffy Bluff Galaxy
- Rightside Down Galaxy
- Cosmic Cove Galaxy
- Wild Glide Galaxy
- Honeybloom Galaxy
- Freezy Flake Galaxy
- Honeyhop Galaxy
- Space Storm Galaxy
- Boo Moon Galaxy
- Upside Dizzy Galaxy
- Fleet Glide Galaxy
- Melty Monster Galaxy
- Slimy Spring Galaxy
Speed Run[edit]
Similar to the Speedy Comet in Super Mario Galaxy, Mario will have a time limit in which to complete an existing level during Speed Runs. However, some levels will now start off with only 30 seconds, forcing the player to collect timers along the way to increase time by 10 seconds. Unlike the first game, the timer stops once the level's objective has been met and the star has appeared. Checkpoints can also be used, assuming they have not been removed.
The galaxies that feature Speed Runs without timers include:
- Bowser Jr.'s Fiery Flotilla - Fiery Flotilla Speed Run
- Hightail Falls Galaxy - Hightail Falls Speed Run
- Rolling Masterpiece Galaxy - Masterpiece Speed Run
- Supermassive Galaxy - Big Wigglers Speed Run
- Throwback Galaxy - Whomp Silver Star Speed Run
- Boss Blitz Galaxy - Throwback Throwdown Speed Run
The galaxies that feature Speed Runs with timers include:
- Sky Station Galaxy - Peewee Piranha Speed Run
- Bowser's Lava Lair - Lava Lair Speed Run
- Bowser's Gravity Gauntlet - Gravity Star Speed Run
- Bowser's Galaxy Generator - Bowser's Big Bad Speed Run
- Stone Cyclone Galaxy - Tox Box Speed Run
Daredevil Run[edit]
The Daredevil Runs from the first game return unchanged for Super Mario Galaxy 2. Most of these missions involve boss fights, though one requires Mario to trek through the entire level and one requires him to clear both the level and a boss.
The galaxies that feature Daredevil Runs include:
- Spin-Dig Galaxy - Digga-Leg's Daredevil Run
- Bowser Jr.'s Fearsome Fleet - Megahammer's Daredevil Bash
- Slipsand Galaxy - Squizzard's Daredevil Run
- Bowser Jr.'s Boom Bunker - Boomsday Machine Daredevil Run
- Battle Belt Galaxy - Mini-Planet Daredevil Run
- Grandmaster Galaxy - The Perfect Run
Purple Coin[edit]
Like in Super Mario Galaxy, Purple Coin missions require Mario to collect 100 purple coins, often within a time limit. Only a few galaxies have these missions now rather than every one. Some of the levels have added Cosmic Clones as well.
The galaxies that feature Purple Coins with no special conditions include:
- Tall Trunk Galaxy - Tall Trunk's Purple Coin Slide
- Sweet Mystery Galaxy - Bulb Berry's Purple Coin Glow
The galaxies that feature Purple Coins with a time limit include:
- Flip-Swap Galaxy - Purple Coin Flip 'n' Sprint
- Flipsville Galaxy - Purple Coin Spin Speed Run
- Starshine Beach Galaxy - Purple Coin Beach Dash
- Clockwork Ruins Galaxy - The Adventure of the Purple Coins
- Rolling Coaster Galaxy - Purple Coins on the Rainbow Road
The galaxies that feature Purple Coins with Cosmic Clones include:
- Puzzle Plank Galaxy - Purple Coin Shadow Vault
- Mario Squared Galaxy - Luigi's Purple Coin Chaos
Romp[edit]
Romp missions require Mario to defeat 30 enemies within 60 seconds. These enemies include Spinies, Crabbers, and Octoombas depending on the mission. For certain levels, Rainbow Stars or a Rock Mushroom may also be provided.
The galaxies that feature Romps include:
- Yoshi Star Galaxy - Spiny Rainbow Romp
- Boulder Bowl Galaxy - Rolling Crabber Romp
- Shiverburn Galaxy - Octo-Army Icy Rainbow Romp
- Flash Black Galaxy - Dark Octo-Army Romp
Cosmic Clone[edit]
Prankster Comets that generate Cosmic Clones require Mario to collect a Power Star the same way he did in the normal mission, only now while being tailed by his dark duplicates. There is a limit to the number of clones that will generate. In addition, the clones will be destroyed whenever Mario reaches certain points of the level or when the star is released.
The galaxies that feature Cosmic Clones include:
- Cloudy Court Galaxy - The Shadow Lining
- Haunty Halls Galaxy - Spooky Cosmic Clone Chase
- Chompworks Galaxy - Cosmic Clones in the Chompworks
- Flip-Out Galaxy - Cosmic Clone Wall Jumpers
Double Time[edit]
Double Time missions are similar to the Fast Foes missions from Super Mario Galaxy, though it is the platforms that are moving faster rather than the enemies. Not only are the levels sped up, they are also extended with an additional segment. 1-up Mushrooms and Checkpoint Flags appear more frequently throughout.
The galaxies that feature Double Time missions include:
- Beat Block Galaxy - Silver Stars in Double Time
- Twisty Trials Galaxy - Turning Turning Double Time
Green Prankster Comets[edit]
When Bowser is defeated again with all 120 Power Stars in tow, an additional scene will play out during the ending where Rosalina tells the Lumas about the Cosmic Jewels. This scene prompts the appearance of Green Prankster Comets in every world. The Green Prankster Comets double the number of stars in each galaxy by hiding Green Power Stars throughout them, often in hard-to-reach or out-of-the-way locations. Collecting these stars is the only way to unlock the path to the Grandmaster Galaxy.
