Pest control is a Minigame wich can be found in the "Minigames" teleport in your spellbook. As soon as you click the teleport, you will find yourself in the Pest Control Minigame.
Your objective is to take down each portal before the time runs out.
3 players are needed for the ship to depart.
Each game you successfully complete will earn you 4 points.
These points can be used to buy items in the Pest Control shop
