To summarize the take on Leggy Parrot Kai by action, he sure did had a rumbly good time taking care of his Whale-sized Tummies along side with his Trunk Maw & Tail Maw if he can reach to it! (May be a rehash of a 2017 art I know, loved, and inspired. Unlike Fory, he hasn't have as much trouble controlling his tummies but has better handling) A Hybrid between a Parrot as the Original probably to feel like a Blowhole, the Elephant to imitate a Land Mammal, a Spider for having 8 Limbs in general (4 Wings/Arms & Four Legs), Kind of a Snake for the Tailmaw but could shift length if it wants to, and of course the Growly tummies with the Largest tongues similar to Whales or maybe Kangaroos for a similar placement if to use them for storage plus alternate between Swimming & Hopping.

To tip you with a drawing that I'll eventually do with full color, I might as well draw a select character of yours to give the treatment of Kai's berry shapeshift poisoning power!
