ok so i was on wikipedia, and i stumbled across this, somewhat of a profile for coco. and its in spoiler tags so you dont have to read it. according to the man himself, Craig:
Spoiler Below "The idea behind Coco is that she was created by a lonely kid trapped on a desert island. Her design elements are made up of the kids thoughts/surroundings. Her tree head = the palm trees on the island, Her airplane body=the dream of being rescued and nightmare of how the kid ended up on the island, Her red beak=the deflated rubber raft that brought the kid to the island, Her shoeless sunburned feet=all the kid stares at all day, and her name Coco = Coconuts, what the kid lived on. As you can tell I think too much about this stuff."
