Like most rhinoceroses, Kuloo is large and gray. He has two short and stubby horns.
Kuloo is shy and stuttering with a good heart.
When Rasha, a young female rhinoceros, begins to pursue Zazu as a mate, the flustered hornbill runs into Kuloo and immediately tries to introduce him to the persistent Rasha. Frightened at the prospect of talking to a female, Kuloo hides behind a tree, though he is awestruck at how beautiful Rasha is. Pretending to be Kuloo, Zazu calls to Rasha, who rams into the tree behind which Kuloo is hiding. Upon seeing each other for the first time, Kuloo and Rasha immediately fall in love.
