Cameo Appearances

The Lost Cases of the Tree House

Numbuh 421 is a Kids Next Door operative.

History[]

He was in the audience up on the Kids Next Door Moonbase in the crossover-episode The Lost Cases of the Tree House. Sector V had recently captured a P.I.N.H.A.T.A., a new piece of villain technology, and was scanning it. In doing so, Dr. Flug appeared on a screen and spoke directly to the KND. Numbuh 421 did not appear taken aback by his sudden appearance.
