Rebbi

Rebbi is an important Nimbi in Super Paper Mario.

While in Sector 7 of The Overthere, Mario encountered a Nimbi fighting the invading Skellobits. Upon Mario's arrival, the Nimbi requested Mario's help in defeating the Skellobits.

Once he did so, the Nimbi - whose name happened to be Rebbi - gave Mario the Red Orb, one of the three orbs required to build the bridge to Grambi's castle. He then flew off and wasn't seen for the rest of the game.
