Yes, I will second the
ball house in Curious George, my kids spent almost an hour there.
Yes, the nametag on JP river adventure was there in August.
The signage throughout Dudley Do Right is funny. There are also two talking puppets there right before you enter the logs... they tell corny jokes.
MIB numerous stuff... look for the green ooze on the ground near the weapon room. Also listen for the two aliens arguing behind the door as you exit the ride. Look at the supposed aliens on the TV screens... some of the 'celebrities" are a hoot. Also, listen to the aliens in the break room, they are funny!
BTTF, tons to look at. ONce you get in the loading office, first look at whose office you are loaded into.. sometimes its Albert Einstien, sometimes its other famous scientists... Look at all the fake props inside.. one was a travel journal, one was a sketch of the flux capacater, one was a old bottle cap, etc.. lots to look at in each office, and there are many offices.
