Yo Gabba Gabba is a group of colorful monster characters who star in a children's educational television show. The members, Muno, Brobee, Toodee, Plex, and Foofa, had a major role in the Season Seventeen episode, "Taming Strange".
In an attempt to rekindle his relationship with his brother, Ike, Kyle Broflovski takes him to a Yo Gabba Gabba! concert. At the concert, Ike goes onstage and "tames Foofa's strange", much to the horror of the other Gabbas and the audience. Foofa then leaves the group, desiring to become "edgier" and have more "sex appeal", despite protests from the others. Foofa goes on to smoke pot, party, and arranges a raunchy performance at the MTV Video Music Awards, with Ike as her manager. The other Gabbas try to convince her not to perform, but to no avail. At the VMAs, Kyle manages to convince Ike that he's trying to grow up too fast, and they reconcile. Foofa, however, is unmoved by this, reveals her dominatrix outfit, and proceeds to perform, as the others watch in horror and disappointment.
Foofa is a female, flower bubble character. Though she is originally innocent, after having her "strange tamed" by Ike, she has a personality shift which makes her want to be more mature and edgier. After leaving the group, she smokes pot, parties, and gives a raunchy performance at the MTV Video Music Awards, much to the protest of the other Gabbas.
Muno is a male, red cyclops character. He has concern for Foofa and works with the other Gabbas to return Foofa to normal. He is the tallest of the Gabbas.
Brobee is a male, green monster character; he is the the smallest and the youngest of the Gabbas. He has concern for Foofa and attempts to return Foofa to normal at the VMAs; alas, she performs anyway as Brobee covers his eyes.
Toodee is a female, blue arctic cat-dragon character. She has concern for Foofa and works with the other Gabbas to return Foofa to normal.
Plex is a male, magic yellow robot; he is the oldest of the Gabbas and their leader. He says that Foofa was traumatized by Ike and watches in horror as she leaves the group to become a more mature performer. Plex and the group tries to prevent her from performing at the VMAs, telling her that she doesn't need to show her strange on television to get attention, but their efforts fail.
