Okay… So I can't remember a lot about this movie, but I saw it on T.V. when I was about 7-9 years old and the puppet in it scared the hell out of me. It wasn't even a horror movie, it was a family film!
The puppet looks like some sort of cat/dog or mammal in a cartoony style. I don't recall ever seeing his legs, but they could possibly have been shown. (Most likely without his top half in the shot.)
He has the ability to appear random places and pop out of anywhere like cupboards, trash cans, lockers etc… just general holes/crevices/places the camera can't see into fully, so it gives the illusion that he disappears into some weird Narnia place like all the good creepy monster puppets.
The puppet is a good guy and helps this kid for some reason, or maybe the kid is helping him? …I just remember, he wasn't the bad guy/villain in the movie.
So the kid in this movie plays baseball or some type of sport because I remember a scene in which he was in the changing rooms in his uniform talking to the creepy puppet that had popped out of a dirty laundry basket or something.
There is another part I remember… The villains/bad guys in the movie that want to capture the puppet for some reason unknown, are in a magic shop or some place that happened to have an ancient scroll depicting the puppet in ancient Egypt, canoeing down the river Nile with the pyramids in the background.
This is all I remember of the movie, I hope somebody can help me! Thanks in advance!
