Chili dog Easter egg

At set intervals when running at top speed, Sonic will briefly present a chili dog to the player for approximately two frames before resuming his regular animation. This also occurs with Sonic's LEGO skin.

Debug Menu

Complete Story Mode, then press the following button sequence on the main menu depending on the system/controller used:

• PS4/PS5:
• Xbox:
• Switch:

This will display a debug menu, which offers a basic stage select and sound test. The stage select allows the user to play any Zone from Story Mode as any character, however character selections are still restricted for character-exclusive Acts. The sound test is very basic and only allows the user to listen to music tracks.

Unused content

Audio

Many unused music tracks exist in the game's files. Some appear to be early revisions of final tunes, while others originate from Sonic the Hedgehog 4. It is speculated that these may have been placeholders during development, or leftovers from promotional builds.
