In La Cucaracula, the third game to feature a crawling nano HEXBUG, a vampire cockroach flits through the corridors of a haunted castle. Working together, the children try to drive him out by turning on the lights in every room, but each time they encounter the cockroach, they lose a piece of their protective garlic in shock — and if their supply is used up, the monster wins!

Luckily, a fresh supply of garlic will be brought in via catapult if the children manage to shoot the vampire cockroach to the moon. Can they brighten the castle before their garlic runs out?
