"Guess I'll go next." You watch Damon taking off his clothes. "Won't be needing them when I become a merman." Damon place his clothes down as he drinks the potion.
"Now all you have to do is go into the water." Said the shopkeeper. "I already know that. This is going to feel weird." Damon then heads, to the water, where Brenda was as you saw him fall.
Damon's legs then fuse together as it became a single limb. Blue scales then appear, on his legs, as his toes becomes his new fins. Damon was now a merman.
You watch Damon swim around and jump, out, of the water, and getting Brenda wet. "Hey watch it." You have a feeling he was enjoying it.
"So this is what it's like to be half fish." You were the only left to drink the potion.
