Ybooma was a Little Green Critter male born in 799 BBY on one of his Uncle Yodatine's deep-space stations. His parents were Yiba and Yoda.
Ybooma developed into a pyromaniac obsessed with detonite. In 794 BBY, he accidentally burned down Yoda's Gimer Plantation. Yiba perished in the flames.
In 783 BBY, Ybooma committed suicide to his guilt over his mother's death. He threw himself off a bridge into a river in a rocky ravine.
Behind the scenes[]
The name Ybooma was evocative of the noise "boom!" and a pun of the character's obsession with explosives.
