Covert uses her students to find an 'invisibility' plant. The Wardens instruct Sadie and Gilbert to find the flower and bring it safely back to the magical realm.

At Sadie's school, Gilbert and Cornelius are overheard arguing by Covert. Despite their best attempts to seem like "normal" animals, Covert is convinced that there is magic at play!

Sadie and Gilbert notice something strange about the kids at school... they're all dancing! Their eyes are glazed over and they are acting like zombies. It must be the potion Sadie and Gilbert dumped down the sink!
