OK her is another one I just thought of. It's animated and its about these kids who find this troll under the bridge who has an AMAZING green thumb and can produce plants from his thumb when he puts his thumb on the ground. I know its not a lot but if anyone can find it I'll be sooo happy Thanks!

Probably this movie A Troll in Central Park (1994) (http://www.imdb.com/title/tt0108395/)

THANK YOU SOO MUCH
Now that I know the name I found the whole movie on YouTube and I'm watching it! Thanks again! :)

No problem :)
