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".
Background
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.

He says that Foofa was traumatized by Ike and watches in horror as she leaves the group to become a more mature performer.
