Koopa Bank Capsule
From the Super Mario Wiki
The Koopa Bank Capsule.
A Koopa Bank Capsule is a yellow Capsule found in Mario Party 5. This item is useful when players have a lot of coins. The player has to throw it on a space, and when a player passes by, he gives the Koopa Bank five coins. If a player has less than five coins when he passes by, he will give all the coins to the Koopa Bank instead. When a player's turn ends on the Koopa Bank Space, he gets all the coins the bank has.
Koopa Banks have also appeared pre-set on the board in earlier Mario Party games, starting with Mario Party 2.
