Grub Guardian is a tower defense game from KingsIsle Entertainment. Defend the grub against swarms of different enemies while you train your Wizard101 Pet or receive free Wizard101 game codes. Grub Guardian is the first minigame that ties directly to a live Wizard101 account. Logging into Grub Guardian allows you to unlock new maps and train your pets for experience parts. Grub Guardian has 28 free maps ranging in difficulty, and every pet has different strengths and abilities. New maps unlock as you progress, and different strategies are needed for new enemies. The game also offers the ability to purchase in-game items and additional maps with KingsIsle's "Crowns" currency. Less
