Prior to the Great Cataclysm, Tiribomba lived and worked in Ta-Metru. He was captured by the Vahki under the command of Makuta Teridax, disguised as Turaga Dume. He was then forced into a Matoran Sphere but was later rescued by the Toa Metru and awakened on the shores of Naho Bay on the island of Mata Nui.
As a consequence of his exposure to the effects of a Matoran Sphere, Tiribomba's size and physical strength was reduced and his memory erased. Nonetheless, he helped in the construction of Ta-Koro, under Turaga Vakama, making use of parts from the Airships used in the Great Rescue.
In Ta-Koro, Tiribomba became a Lava Farmer. Following the defeat of the Bohrok-Kal, he was rebuilt into a stronger form. When the Rahkshi attacked Ta-Koro, Tiribomba was evacuated with the other Matoran.
Return to Metru Nui
Following the Rahkshi's defeat, Tiribomba helped in the construction of Boats to assist in the Matoran's return to Metru Nui. He also assisted in the restoration of Metru Nui, which had been damaged by the Great Cataclysm and subsequent events. He temporarily stopped his work of reconstruction on order of Jaller, to force the Turaga to reveal where the Toa Nuva had gone, but he eventually got back to work.
Subsequent to Teridax's death in the Battle of Bara Magna liberating the inhabitants of the Matoran Universe, Tiribomba and other surviving Matoran of Metru Nui vacated the city to relocate to Spherus Magna.
