Real-Life Relative: Christian Jacobs's son, Oskar, guests stars in "Summer Camp!" as Chauncey, the Aquacadet who models himself after MC Bat Commander.
Squick: Averted in the making-of Slushi commercial (from the "Uberchaun!" episode), according to the Mega64 podcast: the actual slushie used had candy in it to recreate the colors of sushi (watermelon for wasabi, black licorice for seaweed, etc.) with sherberet and ice cream to hold the candy in place. They expected the kids to take a sip, figuring the concoction would be gross, but the kids thought it tasted good, and proceeded to chug it, even after the director yelled "Cut!" The guys said they felt guilty having to pry away the cups because they really didn't want to make more.
Throw It In: In "Cobra Man!" there's a moment where the Aquabats are ripping off their groundskeeper uniforms and the chinstrap on Crash's hat gets caught on his nose. According to the 'bats' commentary it was an accident but it fit the show's humor so well the crew didn't do another take.
