Gopher

Gopher is a resident of the 100 Acre Wood. Though the 100 Acre Wood has been in the previous games, Gopher did not appear until Kingdom Hearts II. He was first met in PIglet's House. Of all residents, he is the only one who literally lives underground, and digs through the ground to make a living. During the Hunny Slider mini-game, Gopher helps by acting as a buffer between Pooh and pieces of wood or other obstacles.

''Gopher is an excavation expert. That is, he's a specialist at digging holes. Whenever you need to find him, just look for a mound of fresh dirt.''

Trivia
