Jack Attack is a demon possessed Jack in the Box from the Demonic Toys film series. Jack is know for his constant psychotic laugh. Jack often pops out like a regular Jack in the box but more intensely to scare his victims. Much like Grizzly Teddy, he usually kills his victims by eating their flesh. When Jack wants to travel somewhere, he'll get out of his box and slither like a snake with a baby rattler at the end of his tail.
