Mystery Box

A rattling box on the beat, then a burst of cartoon goodies.

A mystery box slams onto a lemon field and rattles on every beat until the lid blasts off and a wall of hand-drawn items erupts. An app card swaps one item on a slot reel, a scooter races a countdown, the box lands on a doormat with a DING DONG, and the logo slams in as a sticker.
