America's favorite silly ska-surf-rock band is back in the kid-friendly "The Aquabats! Super Show!," and Jon Heder is dropping in to wreak havoc on the team.

The Aquabats are a super-powered musical superhero group led by vocalist (and "Yo Gabba Gabba!" co-creator) Christian Jacobs. He acts as exec producer on the new show.

The latest episode guest stars Heder ("Napoleon Dynamite"). It airs today at 6:30 pm EST and 11 pm EST as well as Saturday morning at 8 am EST on HUB. The episode also includes Lou Diamond Phillips ("Young Guns," "La Bamba").

In the episode, guitarist Ian Fowles (after singing a Judas Priest-like ditty about brotherhood) runs into his long-lost brother (Heder) who's actually a pretty evil dude. Watch the exclusive clip above.
