In the hieroglyphs in the "Indy room,” Pharaoh Mickey and Slave Donald are on the BACK wall on the opposite side from Indy and Salla, just as you're about to leave that room. It is about 1/3 of the way "up.”

I've seen this one, you really have to know right where to look. The site below has a picture about half way down the page.

That is too cool! I love hidden Mickey's.

I'm probably the last person to notice this, but ...

If you're looking at Muppets, there is a barrier wall over to your left, that divides the Muppet area from that New York Street.

There are giant round plant containers on the wall. One of them is actually an ice cream sundae. Even further down the wall, is an empty ice cream container.

At the Indiana Jones Show, there is a sign on the well that says "Don't pull the rope." Pull the rope! You'll hear something cool!
