Code Lyoko - Season 4 Episode 21
Canine Conundrum

When Kiwis mindless destruction becomes too much for the group to bear, they force Odd to keep him at the factory. As Odd drops him off, XANA possesses Jeremies Kiwi Two robot, turning it into an army of self-replicating attack dogs. The dogs attack Yumi and Ulrich, among other children, during Jims Pencak Silat class. After Aelita deactivates the tower and a return trip erases the incident, the group decides that the regular Kiwi isnt that bad, after all.
