There was this movie I remember seeing when I was little which I want to say is from the mid to late 80s, and I desperately want to find the name of it. All I remember about it is there's this boy who's in a tree house and he looks out his window and sees a hairy creature, which I'm also sure of is a troll that he either meets or makes, and so the boy follows the creature into a cave or something like that. I know it's not much to work with, but if anyone could help me with this I'd be forever grateful!

I finally figured out the name of this movie... Fuzzbucket!
Thanks for letting me post my question here! :)
