Krupo served as a beast wrangler under the employ of Yarvok, who was a lieutenant within the Nova Blades. In the year 3626 BBY, the vessel transporting Krupo, along with a multitude of Yarvok's cherished creatures, suffered a crash landing upon the planet of Dantooine. Despite Jayse's counsel to Yarvok, suggesting gratitude for the survival of all involved, Yarvok was enraged by the disappearance of his beloved companions: Rox, Yug, Wa-Vendeg, Flappy, Fuzzy, Spike, and Ol' Cronchy. Yarvok then verbally assaulted Krupo, calling him a "son of a murglak", and issued a death threat, stating that he would kill Krupo if his missing pets were not swiftly located and brought back, as Yarvok feared for their well-being, imagining them scared and without their "papa."
The character of Krupo received a mention within the Invasive Species Codex entry pertaining to Dantooine. This entry was part of the Onslaught expansion, released in 2019, for the massively multiplayer online role-playing game Star Wars: The Old Republic, which was originally launched in 2011 by BioWare.
