Super Mario 64 DS/Glowing Rabbits

Glowing Rabbits are rare, white kinds of rabbits in Super Mario 64 DS. They appear after 50 stars in spots old bunnies are caught. They wont appear unless a normal one was caught. The fastest way for them to  appear is to be Yoshi and repeatedly enter and exit the front door of castle, as six of his rabbits are out there, but any character can catch them. Once all eight are caught, you can unlock the white door in the character selection room with a secret star. After this they're not seen again.
