Knuckles' Hangout is a dark and murky cave with moss growing there. The only light sources here are a hole in the roof and a burning torch. The furniture are made of rock and include a table, shelf and bench. Weightlifting gear can be found around the place. Also, on the walls are purple crystal clusters.
In Sonic Boom: Shattered Crystal, Knuckles' Hangout is one of the locations that can be visited on the World Map of Scrapyard. Here, the player can play the mini-game "Knuckles' Workout" once ever 24 hours, where the player must rapidly press and to fill up a gauge and earn a Token. Although Knuckles' Hangout can be accessed from when first arriving at Scrapyard, it is first unlocked after the player has completed the Scrapyard act.
- Contrast to popular belief, Knuckles' Hangout is not Knuckles' residence as Bill Freiberger has confirmed in an interview that Knuckles is a wanderer who lives in nature.
- Knuckles' Hangout is the only residence belonging to Team Sonic which has not appeared in any media outside of Sonic Boom: Shattered Crystal.
