Comet, the Roller Skate

You swim up to Comet, the leader of the roller skates. He thanks you for helping get rid of the ice skates, and challenges you to a finwrestling contest. After you lose a few times, he teaches you the classic "Under the Waves" maneuver. You have to modify it a little because you have thumbs, but after a while, you master it.

As you swim away, you notice that your biceps, triceps, and uniceps are all tingling, and you didn't even know you had uniceps.

You acquire an effect: Finstrong (duration: 30 Adventures)
