The Alligator Head is a trap featured in Zombies in Spaceland.
The Alligator Head is activated once the power it turned on, and can be used to crush anything that steps into its mouth after a few seconds, including the player. As the trap doesn't cost any Cash, the player can effectively be used a limitless number of times.
The trap location is found by taking the right door from the map's centre junction. Leading to it located within the Keplar System.
