Snow White Mickey

In one of the first scenes of "Snow White's Scary Adventures", this one is above the mirror.

It a small world - sign

Turn the entrance information sign sideways, and you have a nice hidden mickey!

Philharmagic Mickey

In Philharmagic, the right side of the red curtain. A hidden mickey in a golden french horn.

Its a small Hidden Mickey after all

Well, these aren't really small, they are actually pretty large. In the "Jungle Room" near the end, look left and up. There is a whole vine of hidden mickey heads. This is kind of a bad angle, but you should be able to see it.
