Penguins of Madagascar

This famous foursome. They shared a fairly large house. How the four of them managed to get along was a mystery. Skipper had gone out for a while. Rico wasn't home either, perhaps blowing something up again. Kowalski was in his room reading. Ensign was in his room.

Skipper: Team leader, master of hand-to-hand combat, saboteur. Decisive and cool-headed. He trusts his comrades, but frankly, his weak point is the Ensign...
Kowalski: The brains of the team, the inventor and tactician. He's the smartest, but often misses simple solutions.
Rico: A weapons and explosives specialist. He barely speaks, has a tendency toward madness, and loves dynamite.
Ensign: The youngest and most inexperienced. Good-natured, he often serves as "bait." Very smart, although he hides it under a mask of innocence.
