When the penguins get trapped in the cage, Skipper is on the right (from the viewer though, it would look like he's on the left) but then when Skipper slaps Kowalski, he's on the left (right from the viewer's point-of-view)
This is the 2nd appearance of Officer X of the metropolitan pet & food control.
This is the second time Rico loses his doll to someone else. The first time was on "Penguiner Takes All" to King Julien.
Kowalski: (about Officer X's van) She's... beautiful! (Kowalski gets a glimpse of the van. Suddenly, the background behind him becomes blue with a rainbow and Kowalski smiles dreamily. We then see the van spinning around and then we see Kowalski smiling more)
Skipper: (slaps Kowalski out of his daze) Kowalski!
Officer X: (angrily) I LOVED..THAT VAN!
Kowalski: (gets peeved) Yes, we all love the van. YOU THINK YOU'RE THE ONLY ONE HURTING?
Kowalski: (referring to Officer X's van) So wild, so free..and I know I can tame her!
Skipper: You heard the man, as long as we're outside the zoo, we're considered stray animals!
Kowalski: (sighs) I've never felt so filthy.
Second time Kowalski's been in love. The first time was in "Gone In A Flash" with Doris the Dolphin.
Kowalski falls in love with Officer X's van in this episode, which is very unnatural.
Episode Title: "What Goes Around"
The title is a spin-off on the phrase "What goes around comes around".
