The monster friends are as diverse as the spectrum of colors they come in, and young viewers will easily relate to their individuality. Towering red Cyclops Muno (voiced by Adam Deibert) is always full of fun, but he's also afraid of the shadows he sees in the dark. Natural leader Toodee (Erin Pearce) sometimes forgets that there's fun to be found in sharing, but she always realizes her mistake and makes amends. Foofa (Emma Jacobs) is thoughtful and loving, though she's also been known to throw a tantrum or two. Youngster Brobee (Amos Watene) is often the one in the group to get hurt, but his friends' encouragement gets him going again. And gadget-covered Plex (Christian Jacobs) is always willing to lend a hand to help his friends learn something new.

With its enticingly vibrant characters and simple, retro style, there's no doubt that Yo Gabba Gabba! will beckon to 2- to 4-year-olds, who will revel in the repetition -- which promotes familiarity and confidence. But for the parents of these preschoolers, the show's songs, hip beat or no, may spark decidedly different emotions. Many of the omnipresent tunes are of the one- or two-line variety -- "There's a party in my tummy, so yummy, so yummy," and "Snacky snack snack snack snack," for example -- that are guaranteed to get stuck in your head for hours. (Don't worry, you can always oust it with something by the Wiggles if you get desperate...)
