I dont know if someone already posted this or not. When I was revisiting Halloween town I went to santa claws and left his house and at the top of the screen it said there were rare monsters. They looked like gumball machines there health bars drained quickly. there were 2 one droped a limited capsule (reaction command) and rare capsule, normal capsule and prime (the hardest to get). The monsters name is bulky vender. The lower the HP of the vender the rarer the item.
