Morphing Healing

<Morph!> I yelled. <I think I know what to do. Morph back to human.>

<If he morphs to human, he'll just drown,> Rachel argued.

<No. Morphing uses DNA, right? The basic pattern of the animal. Marco morphs back to human. I don't think the injury will affect him, because it doesn't affect his human DNA. Then, as soon as he can, he morphs back to dolphin. The dolphin body was injured, but the dolphin DNA should be the same. He should be a healthy, normal dolphin again.>

Then Marco began to change. Arms sprouted from his flippers. His face flattened down, with his wide, grinning dolphin mouth shortening to form Marco's own lips. His skin turned pink and his morphing suit appeared.

His shattered, injured tail split in two. Legs formed from the halves, toes appeared. Human toes. At the end of human legs.

<He did it!>

"Yeah, I did it. And now I'm drowning!"
