God this is so underrated...
... I love this thing. First off, Mr. Bungle is classic and you nailed the music here. The monster designs were very "Fosters" which rocked. The animation was spot on, just smooth and well paced. Great timings. I imagine alot of soul went into keying this bitch.
Anyawy. 5 from me, for the backgrounds, overall style, simplicity, and music choice. In my top 3 favourites for Halloween this year.
