Algodoo

Remade from scratch, this simulation has a lot of features like:
-- Eating!
-- Drinking!
-- uhhh... e.c.
Featuring: The guy from the toilet scene!
The stomach can stretch, allowing for a larger volume of food to be stored.
Note:
The physics breaking is techically possible, but I haven't yet experienced it.
Note 2:
Do not eat kitchen utensils. It is bad for him.
