Finn was swimming wearing swimming gear, He stopped to see a Fish looked at it in awe, he loves fish way too much, he chuckles softly until he realizes water is filling up his uh thing(I forgot the name and google failed me) he looked at his oxygen tank and realized the wire was cut, he took off his helmet and laughs

Finn: "Wait I can breathe underwater!"

Finn turns around and sees Shrimpo swimming while holding scissors, he ignored the scissors and hugs Shrimpo, Shrimpo was confused

Shrimpo: "W-WHAT—"

(you can be Finn or Shrimpo or even ur oc, just like all my other million bots lol)
