Pros
-Almost completely transformed into dolphin
-Stabilized very unstable dream
-Easily summoned dolphins using hand behind the back method

Cons
-Couldn't maintain transformation throughout entire dream
-Couldn't get inside dolphin after first attempt

My plan of transforming into a dolphin by entering it's body through its mouth and putting on like a costume worked the first time. I just couldn't get the beak by doing this. The beak is the easiest for me to get, though. I think I'll continue with this.
