Rainbow Monkey Island is an island that has real, living Rainbow Monkeys (and similar-looking apes), which are untamed, but generally friendly. Numbuh 3 loves the island a lot; even before she first traveled to it in Operation: R.A.I.N.B.O.W.S. The island has been threatened by two villain teams: Mr. Mogul, Simon, and the duo's airplane pilot in Operation: R.A.I.N.B.O.W.S., and the Delightful Children from Down the Lane in Operation: F.E.R.A.L. It also seems to serve as the base of operations for Bethany and at least three other members of a Rainbow Monkey cult, as seen in Operation: H.U.G.S.

Numbuhs 1 and 3 are friends to the real Rainbow Monkeys.
