I fed a dolphin fish to lead me to treasure.  Not only did it spiral around my boat very fast, it also, after fed, reached mach 5 and managed to jump out of the water and clear a mountain while looking for treasure.

What I expected to happen was...:
Dolphin goes normal dolphin speeds while receiving fish and looking for treasure.

What actually happened was...:
Dolphin does a 360* spin around my boat around 55mph, and after given fish, proceeds to speed away from me at breakneck speeds and jumps over a mountain due to it's incredible speed accompanied by its ability to jump out of the water.

Steps to Reproduce:
1. Approach a dolphin with fish in hand (The fast spiraling happens almost every time for me.)
2. Feed the dolphin fish (This is the first time the mountain clearing has taken place, i'm not sure how many attempts it would take for it to happen again.)
