Tombo was exiled from his herd for his unruly behavior of squirting water at animals and annoying them. Simba and Nala attempt to re-integrate him into his herd. Tombo's mother doesn't mind him and begs Simba to help her son come back.
A thunderstorm begins to form, the lightning setting the plains afire. Using his water-spraying abilities, Tombo puts out the fire.
With this act, the herd accepts him back, and he is named "Hero of the Year" by the lead Bull Elephant. Instead of spraying others with his water, he uses it only to bathe himself.
Tombo has dark bluish-gray skin, with tusks that haven't grown in yet due to his young age.
His personality isn't all that explored, but one could say he's unyielding and opinionated, since even though he wants to return, he refuses to give up what he loves in order to do so. He also has a fondness for squirting water from his trunk.
