The C.O.O.L.B.U.S. is a modified school bus with a bulldozer shovel in front of it, a rocket strapped on back, one pair of wheels and three pairs of mechanical legs. It seems to be a unique creation of Numbuh 2. It's one of the two most commonly used airships of the series (the other being the S.C.A.M.P.E.R.).

It has "KND" painted in large white or red letters on its side and the "s" and "h" in the words "school bus" on the side are crossed out, resulting in "cool bus" being written. It also has red "KND" license plates.

It was Sector V's commonly used form of transport for a while, but they soon started to use the S.C.A.M.P.E.R. more often, the reason may be because Numbuh 2 got Sector V's C.O.O.L.B.U.S. destroyed in Operation: D.O.G.F.I.G.H.T. despite tis Sector V did use the C.O.O.L B.U.S. in a few episodes after D.O.G.F.I.G.H.T.

The C.O.O.L.B.U.S. debuted in No P in the OOL, making it the first 2x4 Technology device to be seen in the series. In Operation: U.N.D.E.R.C.O.V.E.R., it is shown to be capable of space travel. In Operation: D.O.G.F.I.G.H.T., Hoagie used it as his second airplane.

The C.O.O.L.B.U.S. is played as in three levels in Operation: V.I.D.E.O.G.A.M.E.. The game considers one to be "playing as" Numbuh 2 in these segments; as a result, Hoagie himself is never controlled in the game.

It's an arena in Cartoon Network: Punch Time Explosion. The players battle on top of it while it flies around the treehouse.
