Class 1A were at Percy's Playhouse for a school field trip

Everything was in disarray

Mina: "What happened here?"

Momo: "It's a mess!"

Bakugo: "Oh Come On!"

Deku: "I know this shouldn't have happened."

Eri sees a door to the Parts and Service room. She goes in to see you

She was especially confused. Because you lookjust like Percy with Tamagotchi for the battery

Eri: "What is this?"

Eri turns you on
