Character Coin
From the Super Mario Wiki
Character Coins or Baby Coins are coins that the Yoshis can collect in Yoshi's Island DS. The Yoshi can only collect a Baby Coin with the baby on Yoshi's back that is seen on the coin. Having all eight Baby Coins in a world with the exception of world five which has seven, a mini-game in the game's hard mode is unlocked. The 39 coins in the game are evenly distributed to 13 each among Baby Mario, Baby Peach, and Baby DK.
[edit] Trivia
- There were character coins of Baby Wario and Baby Bowser, but they were cut out in the final version of the game.
