As a part of their plan to distract Robotnik, Dirk and Polo followed Ari and Lupe on Dulcy's back in a Hover Unit to the Doomsday Machine. Once above Robotnik's base, they proceeded to drop mannequins equipped with parachutes above the base to distract Robotnik's forces. Dirk and Polo later landed on the Doomsday Machine themselves, but were quickly detected and arrested by Swat-Bots. After Sonic and Sally used the power of the Deep Power Stones and began destroying the Doomsday Machine however, Dirk, Polo, Ari and Lupe escaped captivity and fled to a Hover Unit, which they used to fly away in.
