Glowing rabbit

"But don't even get any ideas about catching all of us, OK, bub? It's impossible!"

- Glowing rabbit

Glowing rabbits are a rare, shiny type of rabbit that appears only in Super Mario 64 DS. These rabbits appear to be white with sparkles appearing from their bodies. Much like the regular rabbits, glowing rabbits are modeled after MIPS from the original game.

When 50 Power Stars are collected, glowing rabbits start to randomly appear around the Mushroom Castle in place of the player characters' other rabbits once that rabbit has been caught at least once. Each time the area a rabbit is in is loaded, there is a 1/32 chance for each eligible rabbit to be glowing, or a 1/16 chance if the player has collected at least 80 Stars. This means it can be more efficient to wait to search for the glowing rabbits until more Stars have been collected. There are eight glowing rabbits in total. When any glowing rabbit before the eighth one is caught, the player gets a chance to save their progress. Once all eight glowing rabbits are caught, the player is rewarded with a key that unlocks the last door in the princess's room, which houses a secret Power Star. Glowing rabbits no longer appear after the player finds all of them, and Boo laughs will be heard if the player enters the room again after obtaining its Star.

The final glowing rabbit caught states that it is the eldest of the glowing rabbits. Additionally, they appear to be related to each other and are all male, as each rabbit then before the last one states that it is the "second fastest of [its] eight brothers."

Trivia

 * It is possible to collect all eight glowing rabbits by repeatedly respawning a single rabbit or set of rabbits until one generates as glowing eight times. For example, as Yoshi, the player can exit the castle's front doors, after which three rabbits are always in the Castle Grounds. If one is glowing, the player can catch it. After doing so, the player can reenter the castle and then exit it again. They can continue doing this until they find another glowing rabbit and catch that one.
 * By using a certain method involving restarting the game at certain points, the RNG of the rabbits can be manipulated to guarantee two glowing rabbits in the Castle Grounds each time the manipulation is completed. This allows glowing rabbits to be caught much more quickly and reliably.
