Bibo, a young rokkna of the male variety, became the adopted companion of Neeku Vozo during 34 ABY. He was discovered within a damaged Z-95 Headhunter that had been recovered by Synara San from the Karavian Trench located in the ocean of Castilon, which ultimately led to him being on the Colossus. Vozo, upon first seeing the young rokkna, felt an immediate connection and chose to keep him as a pet, giving him the name Bibo. This decision, however, provoked the anger of his mother, a fully grown rokkna, who threatened the entire platform in an attempt to get Bibo back. Vozo, understanding that Bibo was the creature's offspring, ultimately released him.
Following the sabotage of the Colossus, Kazuda Xiono inquired about Vozo's friendships, prompting the mechanic to bring up a certain chair, Buggles, and express his affection for Bibo. Vozo then wondered about Bibo's current activities.
