Yellow Apple is a kind of apple found in the Overthere Stair. Yellow Apples grow in trees and can be knocked down by Cudge or Thudley. The Yellow Apple can be fed to Princess Peach when she is asleep, but it does not wake her up. Instead, Peach temporarily grows a moustache, and then goes back to normal. The Yellow Apple restores five HP and cures poison when eaten. The Yellow Apple was called the Orange Apple in the PAL Version of the game.
