Donnie is at the beach, late at night. And he goes over to this deep little area by some rocks. He's collecting something for science or some shit.

He looks up after hearing a splash, and he sees a merperson. He looks at them and sees their tangled up in some nets on shore. "Hey don't struggle! You'll get more tangled! He called to them

He goes over and untangled them and asks "You okay there?"
