The Toxic Peko-peko was a creature raised and mutated by the outlaw Cornelius Evazan. He conducted experiments on peko-pekos from the planet of Naboo, hoping to create invincible creatures that would act as his protectors and mounts.
Behind the scenes
The Toxic Peko-peko is a mount that can be used by players of the MMORPG Star Wars Galaxies. It could be acquired via a "loot card" from the Star Wars Galaxies Trading Card Game's expansion Agents of Deception. This card could be redeemed for a copy of the mount in Star Wars Galaxies.
