This is the Penguins' Head Quarters. There are currently four penguins residing here (Skipper, Kowalski, Rico, and Private). In the first Madagascar movie the HQ still hadn't been built, as the penguins only had a tunnel under the fish bowl, which they apparently planned to use to get to Antarctica, although they resurfaced in the ex-zebra habitat. It is unknown if part of the tunnel still exists and leads to the nowaday llama habitat.
Exterior
The habitat is a very simple and comfy H.Q. The main entrance is a hole in the floor of the habitat covered by a fish bowl. It is unknown why Alice or other humans do not notice the penguins missing from the ice, as they sleep in the HQ and are seen in the HQ for most of the day. Acording to humans there should not be a room (with 13 levels beneath that) under the ice.
Interior
Inside the habitat there are four vertical bunks in the wall each with a pillow and blanket, on one side of the bunks there is a ladder leading up to the main entrance, on the other there is a large door and a clock. On the wall near the ladder there is a large fish mounted on a a plaque reading "Private's First Prize". On the wall opposite the mounted fish, there is a Television with a VCR / DVD player, a large radio and megaphone on top of a concrete block and behind those a jumble of wires, a fork acting for a missing piece of wire, and an electrical box. On the wall opposite the bunks there are four portholes looking out into the water surrounding the habitat, and a periscope that looks around the outside part of the habitat. On the roof there are many pipes and wires, and a large light. The furniture inside varies and can include a refrigerator, an oil drum, a square metal plate suspended by a concrete block acting as a table, four concrete blocks around the "table" for chairs, and a checkerboard held up by another concrete block that Kowalski uses for a small laboratory, his abacus, or talking spellchecker.
Entrances
- Main Entrance- The main entrance is under the fish dish on the penguin's habitat, which on cases of lockdown has nails bolted down tight to prevent any intruders.
- Tunnel 13b- Revealed in The Return of the Revenge of Dr. Blowhole, it is located next to the subway. According to Skipper, there is no way anyone can get through it, but Blowhole surpasses the security system in his Subterranean Attack Pod after using beach balls as decoys. It is armed with enemy-seeking missiles, flamethrowers, etc.
- Sewers- Revealed in Huffin and Puffin. When a password is pressed on a phone, the trash can nearby moves over, revealing an elevator. There are many traps & every single one are aligned in such a dangerous order that Kowalski had quoted: "no one could possibly get through, not even us... oh wait.".
- There are also many other unnamed tunnels, including the one they were digging when they found the entrance to Buck Rockgut's cave in The Red Squirrel.
Tunnels/Other Rooms
What is behind the door varies also, and can be a passage running under the zoo, a room with many pipes, a furnace, and spikes on the roof, a restroom, or a laboratory. The habitat is also rigged with booby traps such as spoons that shoot out from behind the mounted fish, and a laundry basket and a plastic crate that fall from the roof. It also appears that Skipper has a remote that flips part of one of the walls to reveal an impressive array of gadgets, weaponry, and explosives, but on one occassion showed a variety of chemicals. It is uncertain what is behind the plaque - it has been a tunnel to and from various other habitats, an entrance to the sewers and also a safe. The best explanation is that the tunnel splits off into numerous directions, but the safe appears right at the opening, blocking the way.
