At Disneyland, The Many Adventures of Winnie the Pooh replaced Country Bear Jamboree, and we had noticed that some signs of the old attraction, such as the ropes coming down from the ceiling, were incorporated into the new ride. A CM told us that if we looked hard enough, we could find Melvin, Buff and Max still hanging on the wall somewhere inside the ride. We found them. You have to look straight up as you exit the heffalumps and woozles room, but they are there. You pass right under them.
I'm told there are a couple of good hidden mickeys on the ride, too, but we haven't found them.
