Banktoad

The Banktoad was a green toad that appeared in Super Mario Galaxy 2. He is very similar to Mailtoad.

When a player collects some Star Bits, instead of carrying them around with them, they could deposit their star bits to Banktoad at Starship Mario. They could also withdraw their star bits as well.

For every thousand or 2 thousand star bits a player deposits to banktoad, he will get different costumes that he'll wear. Also when a player deposits 9999 star bits to banktoad after collecting the Comet Medal on the Grandmaster Galaxy, the comet for the Grandmaster Galaxy is unlocked.
