Cotton for fabric! Stuffing in the tail to make it stick out, Dood! Pattern, hm... how about 2 full patterns? One of the Front and one for the back, Dood? If not, how about 3 patterns? One for the blue that shows in front, one for the white stomach and shorts and the last for the blue back part dood? Does that make sense? Or maybe something similar to feetie pajamas...Dood!
I suggest you make some kinda opening in the flippers so they
can kinda take them off partly so they can free their hands so they can eat and stuff, Dood! ^^
