Wizard101 is an online, Wizard school adventure with collectible card magic, wizard duels, and far off worlds! The game allows players to create a student Wizard in an attempt to save Wizard City and explore many different worlds.
Both of my boys are avid players and asked if they could have Wizard101 Water Bottles for School when I asked if they wanted superhero/cartoon/themed bottles. You have lots of coffee mugs but no water or sports bottles. I'm just guessing that you have a few more kids out there playing the game than mine that wouldn't mind sporting a bottle at school.
