Gengu runs the Toy shop in Dream Land (known as "Gengu's Toy Store"). In the episode Kirby's Pet Peeve, he mysteriously finds a box from Nightmare Enterprises holding a toy that Sir Ebrum and Lady Like bought for Kirby while checking his inventory. Gengu and Tuggle played an important role in the exposition of Snack Attack - Part I, after Tiff berates them for throwing their stock away and harming the environment. Gengu is also shown to have skills as a mechanic.
