Epcot

On the lower level in the Manatee viewing area, there are lit posters on the walls to the left and right as you leave. There is a Hidden Mickey on the left side in the speed limit area as shown.

Inside The Seas with Nemo & Friends Pavilion, in the waiting room for "Turtle Talk with Crush," a tiny classic Mickey is in the pink and brown coral in the first window painting to the right as you enter the room. At the lower part of the painting, the Mickey is left of the third tallest (leftmost) blue tube, about one quarter of the distance up the side of the tube. Mickey is slanted to his right.

During the "Behind the Seeds" tour, the tour guide will show you a growing container that shapes cucumbers into classic Mickeys. Disney knows how to grow cool cucumbers!

In the Standby queue, a tiny white classic Mickey is on the right wall above a white vertical dashed line. Look for the people drawing concept art in the right wall mural photo collage. This white Hidden Mickey is above the left forearm of a girl drawing on white paper in the middle of the collage photos.
