Carlos Pena Jr. is preparing to hurtle through space…

The 23-year-old singer/actor/dancer of Spanish, Venezuelan and Dominican descent, a two-time Nickelodeon Kids’ Choice Award nominee this year, and his fellow Big Time Rush band members will be guest-starring on an upcoming episode of Nickelodeon’s Marvin Marvin special.

In the episode, Marvin (Lucas Cruikshank) and Teri (Victory Van Tuyl) attend a Big Time Rush concert and learn that Pena and his fellow BTR members have been kidnapped by the evil Klerg, who are on the hunt to find Klutonians. And when Teri gets mistaken for a Klutonian, it’s up to Marvin to save her and the guys.

In the recently released trailer, Pena and the BTR gang appear disheveled after being stuck on an asteroid. And, they perform a song as well.

The hour-long Marvin Marvin special, entitled “Big Time Marvin,” premieres Saturday, March 30 at 8:00 pm ET on Nickelodeon.
