He was to appear caged in the early stages of Dark Beauty Castle (at the beginning of the game) alongside Gus (who was originally supposed to be caged just like the other Gremlins) and another scrapped Gremlin named Jamface (who later appeared in Epic Mickey 2: The Power of Two). Either Barry or Jamface would lower a bridge to the exit, making exiting the area easy.
According to the Game Informer issue, Barry would accompany Jamface and other Gremlins you rescued in the level and tear down Small Pete's blimp.
In the PC files of Epic Mickey 2, Barry along with many other scrapped Gremlins are mentioned. In the files, an unused line is spoken by Gus involving Barry and a long lost Gremlin Vault! "Oh look, it's one of the long lost Gremlin Vaults. I think it was Gremlin Barry who first built it, way back in the day!"
