This is excellent.
The animation is fantastic, the sound effects are well chosen and sound nice.
It's a quirky little story with just good little jokes in many parts.
I just really liked it as a cute little thing, and you should definitely enter it in some festivals (like nicktoons animation festival if the due date isn't already passed)
Anyway, you've got my five, great job.
BTW, why was there gold inside the tree? was that just to be random?
