A Guardian Defense game unlike any other, new from KingsIsle Entertainment!

Defend the grub against swarms of different enemies while you train your Wizard101 pet or play to receive free Wizard101 game codes.

Grub Guardian is the first mini game that ties directly to your live Wizard101 account! Logging into Grub Guardian allows you to unlock new maps as well as train your pets for experience points. Please be aware - you will not be able to log into Grub Guardian and Wizard101 at the same time. If you do not have a Wizard101 account, you can create one, but non-logged in players can still play a limited number of Grub Guardian maps for Wizard101 game codes.
