Pink River dolphin

First of all, my pink river dolphins will change slowly. It will take about 10,000 years to grow into a mix of a pink river dolphin and a turtle. The dolphin will grow to have a shell like a turtle. The shell will have little designs on it and the shell will still be green as a turtle would. Also, the shell will help the dolphin by protecting it a little bit with the predators which is black camins, large sharks, and jaguars. Pink river dolphins don't have fins, so they still don't have fins, they have humps on their back and their tail fin is still there. The dolphin/turtle will have the turtle legs/fins too. The head will be like a turtle's head which is round and the nose is the same as a normal turtle, it will have two eyes as well.
