Description of Experiment: Mouth stitched closed and to add a little of happiness to subject's face, we placed a piece of tape over his mouth with a little smile. Stomach has been cup up and organs have been moved about to make way for a fully working stomach mouth, has a mind of its own, can speak and eats for the both of them. Needs to be fed regularly.
History: Slippery thing this one was, was finally dragged down to the lab and locked up, research was made and found a nice experiment that would suit him. When subject woke up, he was incredibly freaked out but was suddenly slapped still by the tongue from his stomach mouth, turns out that the mouth has its own working mind. Teruteru has then locked up once again and his only source of entertainment is his stomach mouth. He was provided with pen and whiteboard if he needs to communicate, his stomach mouth's tongue seems to like licking him all over and somebody else is in the cell, the tongue will try it's best to lick them too, usually turning out to be an incredibly awkward situation.
