I really liked the first part. Colorful, fun, and energetic.
Then... the lavender town theme started playing and... it was just fucking scary from then on.
But I must ask: Was that your point? To show how disgusting and awful, hoarding everything on planet earth. if so you made your point... very well.
The end... just scared me. alot.
But it was a decent animation and I enjoyed the first half of it.
