The Penguins of Madagascar/Trivia

The Danza: Fred Stoller as Fred the Squirrel.
Fake Brit: Private's VA, James Patrick Stuart, is from California and is only half-British. Lampshaded during "Hard Boiled Eggy" when Skipper notes Eggy picked up "an adorably fake British accent" from Private.
Hey, It's That Voice!:
- Kowalski is Jeff Bennett.
  - In German, he's voiced by Oliver Feld, who voiced another of Bennett's characters: Johnny Bravo.
  - In Spain however, Private's voice actor (Javier Viñas) was Johnny Bravo.
  - Oliver Feld is also the German voice of Stimpy from Ren and Stimpy... and so is the Mexican voice of Rico, José Luis Orozco
- Rico is John Dimaggio.
- Maurice is Kevin Michael Richardson.
- Marlene is voiced by Nicole Sullivan, who also voiced Shego and Mira Nova. Her feral side is voiced by animal noise-creator extraordinaire Dee Bradley Baker.
- Doctor Blowhole's VA, one Neil Patrick Harris, played another doctor... And yet another doctor before anything else.
  - And Jim Cummings voiced his computer.

- Kari Wahlgren voices Kitka the Falcon
- Freddie's mom is Alice
- And Diedrich Bader as the boss rat
The Other Darrin: Julien, Mort, Private and Kowalski were all re-cast from the movies. In an interesting inversion, this actually meant that the latter two went from being voiced by Dream Works staff to professional voice actors.
Talking to Himself:
- Joey and Private are both voiced by James Patrick Stuart. They have a dialogue in "Kanga Management".
- John DiMaggio also voices Burt the elephant. However, Rico and Burt have rarely been in scenes together, and have never conversed.
Title's the Same: My Little Pony: Friendship is Magic and Phineas and Ferb have episodes titled "It's About Time"; all three episodes deal with time travel in a sense.
