Tip-Top Shape

S2, E21: It's time for the annual physical at Kadic Academy! XANA possesses the school nurse, Yollanda, and she captures Aelita. Her goal is to get Aelita to Lyoko and hand her over to the Scyphozoa. For Jeremy, there is only one possible solution -- they must prevent the school nurse from reaching the scanner room! He decides to put a project he's been working on for some time into action... he activates a tower for his own use, then pixelizes Odd, giving him the same powers as someone possessed by XANA. Odd can now fight Yollanda on equal terms! Unfortunately, XANA has some ideas of its own to fight back against Jeremy...
