Numbuh 11-Teen is a Kids Next Door operative, a member of Sector P.h.d who went into the Clothes rack world to study the Poorly Dressed.
Biography
She was sent into Le Sissie to study among the "Poorly Dressed" and rescued Numbuh 5 after she had been captured by them. She said that they had become wild and unruly for a while now.

When Numbuh 5 told them they had to leave the store or be trapped in it forever, Numbuh 11-Teen explained that there is a prophecy that the Poorly Dressed follow: good clothes come to those who wait. She is able to communicate with them in a language made up of various sounds and gestures. However, the Poorly Dressed do speak - though a limited amount of - English. They were rescued by the rest of Sector V and the SKWID Squad right before the bridge, which led to the store, was blown up (Operation: B.R.I.D.G.E.).
Trivia
