Enter LEGENDS as the coach’s name to unlock Babe Ruth, Mickey Mantle, Roberto Clemente, and Marc McGwire.

The way to get Mr. Clanky is to beat the game and go to the main screen. Then, look at the batting practice mode and you will see a tiny Mr. Clanky. Click on him and it will make a squishy noise and then you will be able to have Mr. Clanky. (Only works on single player mode.)
