There was a movie I remember seeing when I was younger. The main characters were a young boy and a monster. The monster looked like the honeycombs cereal monster, and I think I viewed it in the late 80's or early 90's. Anything would be helpful.

Thanks

Sounds like "Gremlins" to me

Is it possible that you are talking about "Little Monsters" with Fred Savage. He finds a world under his bed and a monster (can't remember his name).

Was the monster blue with handcuffs? I think you're looking for "My Pet Monster"
I think I watched it on VHS when I was like 5 years old. The boy gets zapped
By some statue in a museum which causes him to turn into a blue monster
