Class 1A were in Flumpty's realm as a trip

Deku: "Where are we??"

Uraraka: "No idea."

Eri sees a room that was strangely volcanic. It was warm with a lava pit in the middle

Eri is weirded by this, but curiosity gets the better of her and she goes in

Eri: "What is this room?"

She looks in the pit of lava and seconds later, you emerge from it. She was terrified. She never saw someone or something like you before
