In front of the "Song of the Rainforest" area, on a tree to the right of the Grandmother Willow tree, a lizard above the "Giant Cockroach" sign has a classic Mickey above its front leg. Several other smaller spots on the lizard resemble Mickey.
Examine the tree with "The Song of the Rainforest" sign (the Grandmother Willow tree). A side-profile Mickey indentation appears on the tree under the sign and to the lower right (as you face her) of Grandmother Willow's face.
