Didn't get enough Neil Patrick Harris on Monday? Nickelodeon has a one-hour special, Penguins of Madagascar: Blowhole Strikes Back! Here are the deets:

Neil Patrick Harris (How I Met Your Mother) returns as the title characters' sinister nemesis, Dr. Blowhole, in Nickelodeon's brand-new Penguins of Madagascar special, "Blowhole Strikes Back," premiering Friday, Sept. 9, at 8:00 p.m. (ET/PT). The hour-long special features Harris performing in four original musical numbers, two of which he is singing alongside The Penguins of Madagascar characters...

"Our viewers loved Dr. Blowhole in the first special, so we were excited to bring the character back and work with the very talented Neil Patrick Harris again," said Brown Johnson, President, Animation, Nickelodeon. "In this second special, he has expanded his role with unforgettable vocal performances, including a stand-out power ballad."

In the special, Skipper arrives in Shanghai on a super secret solo mission that leads him waddling right into a Dr. Blowhole trap. Without his men, who are back at the zoo, he is helpless and his memory gets wiped away by Blowhole's "Mind-Jacker." Blowhole's despicable plan uses Skipper's memories to locate Kowalski, Private and Rico, blast them with his "Diabologizer," and render them evil monsters who destroy their headquarters. The lyrics from the special-which includes six original songs-were written by series executive producers Robert Schooley and Mark McCorkle and composed by Adam Berry, who recently won a Daytime Emmy Award for his work on the series.

Also at 9 PM, Syfy is showing another original movie, Jabberwock. Featuring Tahmoh Penikett! We were wondering what happened to Tahmoh.

Jabberwock, premiering Saturday, September 10, at 9PM (ET/PT), features the horrifying Jabberwock (from the classic Alice in Wonderland stories by Lewis Carroll), a black-eyed winged monster with the body of a dragon and the head of a gruesome insect. In the movie, a peaceful man (Tahmoh Penikett) wields the all-powerful Vorpal sword to rescue the woman he loves — taken by the Jabberwock into its hideous lair. Jabberwock, a production of American World Pictures, also stars Kacey Barnfield (Resident Evil).

A third option at 9 PM: a new Supah Ninjas on Nickelodeon.
