This papercraft is Mr. Patch, a recurring boss character who debuted in Banjo-Tooie video game series as the boss of Witchyworld, the paper model created by 966623. Later on in the Banjo-Kazooie series, Mr. Patch appeared as a boss in Banjo-Kazooie: Nuts & Bolts, being featured in Nutty Acres and, to an extent, Banjoland. In both of the games his weakness lies in his patches.
Mr. Patch is a large inflatable dinosaur, specifically a T-Rex. He is crafted of shiny yellow and green fabric. His body is ridden with holes that have been covered up and reinforced by colorful patches. He has bright red eyes and large ridges running across his back and a mouth full of white, blunt teeth. As evidenced by his behavior in Banjo-Tooie, he generally doesn't accept humor.
In Banjo-Kazooie: Nuts & Bolts, Mr. Patch's design was updated to give him a slightly more menacing appearance and to match the more angular art style of the game. In addition to the slight changes made to his body structure, minor details were added, such as yellow eyelids, claws on his hands and feet, and stitches running across parts of his body. The placement of many of his patches have changed, as has the location of his plug, which has been moved from in between his legs to the center of his chest. [Source: wikia]
