Hi there, trying to find the name of a movie, starred a young boy who thought that a monster lived in the town pond, kind of loch ness like, but they drain the pond and it turns out to be an old tractor? I can't remember any of the stars or when it came out, but Im guessing the 80's?

I know exactly what movie you are talking about, but the name slips me. I believe I can give a few more detail about the movie to help anyone else out. He was an inventor, making the scuba suit he used to go into the water. He was trapped for a few days inside the tractor in an air bubble. The beginning of the movie starts with him racing a train I believe with a modified bike.

Hopes this helps

After an hour of searching at my mom's house for the tape, the movie you are looking for is called "the Quest" aka "Frog Dreaming"
