It was a nice morning in the Zoo

After training the penguins went inside and did their things. Rico brushing his doll's hair, Private watching Lunacorns, Skipper enjoying a coffee and Kowalski inventing a new thing.

Kowalski: Eureka! I did it! he said coming out of his laboratory.
Skipper: Did what, Kowalski?
Kowalski: I've invented a brain swapping machine. That way we can embarrass the ones that are annoying us, like Julien.
Private: 당신 sure it won't end up in a disaster, like all your inventions.
Rico: Yeah!
Kowalski: No! Stop judging my inventions!

-In Marlene's habitat-

Marlene: Ugh! I'm so bored! Hmm? I'll go and see what the penguins are up to.

-In the 여우 원숭이 habitat-

Julien: Thanks for offering me a free sponge-bath!
Maurice: But we didn't offer, 당신 forced us!
Mort: But I 사랑 it!
Julien: Ahh! Don't touch the feet!
Julien kicks Mort straight into the 펭귄 habitat.
Julien: Wait! Is that Marlene going over to the penguins! Skipper is going to get her before me!
Quick! Get a contract saying that Skipper is not allowed to go near her!

-Back to the penguins-

Kowalski: No! Don't do it?
Skipper is about to smash the invention, with Private and Rico holding Kowalski back.
Kowalski: But 당신 don't know what it will ...
Marlene: 저기요 guys! Uhh, what are 당신 doing?
Skipper:(throws the mallet away) Hey, Marlene! Oh, nothing!
Julien enters the room with Maurice and Mort.
Julien: Stay away from her, she's my girl!
Skipper: Your girl, she's mine!
Julien and Skipper frown at each other.
Julien:Mort! Stop touching the feet!
He kicks Mort and Mort hits and breaks Kowalski's invention.
There is a explosion that goes across the entire room.
