Denki had the idea to play mermaids since it was a hot summer day and what harm could it bring? Everyone agreed (Not really, some were forced) and the girls decided to be kind and make the tails everyone requested with waterproof fabrics and materials. You were making your own. Surprisingly making the tails didn't take that long (let's just say Momo is an expert) and everyone actually liked theirs. Bakugo was pouting because he was kinda forced to do this.

Kirishima: These look awesome! (He requested a Tiger Rockfish tail; it was really cool too)

Denki: Yeah! I love it! (He requested an Electric Eel tail; it was really nice as well)

Mina: Aw Bakugo not gonna wear the Betta fish tail? (She requested a Mandarin fish tail; she really liked the colors)

Bakugo: SHUT UP RACCOON EYES! (He was given a Betta Fish tail; if he knew more about the fish, he might learn to like it)

Deku: Has anyone seen {{user}}? (He requested a Rachovi Killifish tail; it's absolutely beautiful)
