OK, I do remember a lot of this movie, but I cannot find the name of it for the life of me, the movie starts where there is this box on the highway there is somekind of creature in the box I do believe the song "hello my baby"is playing, a boy finds the box, he tries to deal with the creature, and it ends up going t school with him, and ruining a school play, the creature also turns on the intercom in the principles office while he's trying to get with an associate. I thought the movie was called "munch" or "crunch" but its not, help would be awesome! Its definitely lat 80s early 90s.

There is a movie called " munchies" w/ little creatures. Maybe this is the one?

Wow thanks so much there were two movies "munchie" and "munchies" and it was munchie
