Whoa, alot of good episode ideas, I'm loving them! But how about a Halloween special ae? Here's my idea, probably not the best though lol.
One day, the Penguins are rounded up for another shot. Oh, boy. This time, however, Skipper goes on to get his shot without running away. However, the Zoo Vet accidentally injects the wrong shot into Skipper while the other Penguins have the correct ones. Back at the Penguin Habitat, Skipper begins feeling ill. However, Skipper convinces them that he feels fine and decides to do some training. As they do, Skipper ends up fainting. He is then sent to the Zoo Vet, where he dies because of what was injected into him. The Penguins are then saddened and offer Kowalski to be the new leader of the team. He agrees to do so. However, late that night, Skipper comes back to life as a zombie! The shot given to him was a zombie virus! Over at Marlene's Habitat, zombie Skipper comes in but Marlene manages to escape from him! She rushes over to the Penguin Habitat and tells them that Skipper is a zombie. Skipper then comes in, followed by Maurice and Mort 9who have now become zombies) and the trio of Penguins and Marlene manage to escape. However, Private gets captured before he can make it out and becomes a zombie! Kowalski, Rico and Marlene run into a frightened King Julien, who soon joins them in their run. However, King Julien turns into a zombie and begins singing Michael Jackson's Thriller while dancing with zombies behind him! Rico tries to attack the zombies with explosives, but he becomes a zombie and now it's only Kowalski and Marlene left. Oh, what will happen?
I know it seems a bit crappy, but I like wrote this in one day lol.
