- The legs are now hybrid between flippers and legs. The shoulder joint can rotate and open up. When in water, it can spread out the front legs like wings and use them to propel/guide itself. The hind legs can stretch backwards and perform the “dolphin kick” along with its tail to propel itself.
- The tail will have fins.
- Added spinal fins for stabilization in water.
- Widened its mouth and added gills on its neck.
- Removed furs. Its dermis will be smooth and rubbery (sort of like whales or sharks)
