Skorca!.While alone on aerial recon duty one night, Private sees a flying orca. He alerts all of the zoo animals to the presence of the predator, which Julien dubs a "skorca", a contraction of "sky orca". While the penguins set off to track down the skorca, Julien engages the services of Joey the kangaroo to eliminate the threat. After discovering that Private consumed an entire box of "Winkys" during his patrol the penguins believe the skorca sighting was a hallucination resulting from a sugar high. They change their minds when they see the skorca, which is actually just a large parade balloon. During a fight with Joey for the privilege of destroying the skorca, Private pops the balloon and he flies away with it. Believing he is dead, the penguins hold a memorial service for Private but he returns during the service with part of the skorca and is treated as a hero.
