The Amazing Spiez S02 Ep22 - Operation: No Pal In Principal

A mysterious space orb lands in the desert and Jerry sends the spies to investigate. After picking it up, the spies head back to school for lunch. But the orb creates an evil duplicate of Principal Shields, and turns all the students into zombies. Meanwhile, Cal has made a speech for an assembly at Southdale. He is still inside the locked school, but doesn't notice anything. Luckily, the spies manage to defeat the orb, send it to WOOHP, save the school and keep their dad from finding out their secret about being spies.

In the B-story, Tony struggles to find the goal he wants to achieve in his future for a 500-word essay.
