4x15 - Code Lyoko

Odd tries to take Kiwi to Lyoko, but ends up absorbing him instead. As a result, Odd slowly begins to take on dog traits, such as enhanced smell and scratching himself with his foot. While Jeremy works on separating the two, X.A.N.A. possesses a biker gang to attack Yumi. When Ulrich and Aelita arrive to Lyoko, they are confronted by William and three Tarantulas. Jeremy manages to split Odd and Kiwi while Aelita deactivates the tower.
