Clank's subconscious was part of Clank's deep mind. Clank was presumably set to sleep by Orvus, so that Clank could stretch his abilities and fight enemies with his new skills. Qwark appeared as an enemy after Clank imagined somebody he hated a lot. The subconscious seemed very futuristic, with a white, computerized theme. There were several surreal, wavy platforms, although the rest seemed to recreate the Great Clock.
There were screens showing past appearances of Clank with friends.
Orvus had programmed a replica of himself to appear in Clank's subconscious.
- During Clank's final visit to his subconscious, the items that The Plumber pulled out the pipe included Qwark's book, Body By Qwark, the broken speeder Ratchet and Clank built at the beginning of Ratchet & Clank Future: Tools of Destruction, Emperor Tachyon's crown, the Dimensionator, and Ratchet's OmniWrench Millennium 12. The pipe itself and the sound made when Clank fell down.
- The Insomniac Museum in A Crack in Time looked a lot like the subconscious, this was why when you opened the map, it will show the Great Clock.
