He is influenced by many things. He has some eel, also threw in some some jelly fish and octopus/squid. Basically I was him aquatic-ish but to also have the ability to walk upright at the beginning of the short. Also flexibility is important because I want him to really squash and stretch.
When he returns to the water and loses his little suit his arms/legs will become him tentacles and he'll move probably similar to a squid. But this is all up in the air and animation tests will polish this chaos in my head.
