OK so there is this movie that I'm trying to find. It's a space alien, / type thing going on. It involves a boy and a ship that crashes into his backyard. And the things in the ship take over the people in his town. There is one part of the movie when the teacher eats a frog in the closet. The kid and the school nurse try to save everyone. It had to be around 1985 or so.

Might be one of the following. I think the second link for sure.
