The Halloween Jello Mold Brain measures 21x18.5x10 cm (lxwxd).
If the man with two brains had known that... then he could have used our Halloween Jello Mold Brain to coagulate them in his kitchen instead of working so hard to steal them from other people! By the way, human grey matter does not function particularly well at high temperatures, which is why the Halloween Jello Mold Brain is not dishwasher-proof. Use the Jello Mold to separate the mice from the men: the men will be spooning up brain jelly as fast as they can.
