Yu-Gi-Oh! - Duel 021

Reason for challenge
Kujirada's Black Star wants more digital pets as food.

The events

 * Black Star eats Jonouchi's pet, which is unseen.
 * Soon after, it eats Anzu's pet Peachy (Sumomo-chan)
 * Black Star goes to eat Yugi's pet, U2. However, U2 upgrades to a stronger form (similar to how Yugi turns into Yami) thanks to the data it collected by Jonouchi's pet.
 * The upgraded U2 attacks and destroys the Black Star. No penalty game needed.
