While most power-ups are universal, some items or environmental interactions are specifically tied to a character's abilities or a team's unique objectives. These aren't 'items' in the traditional sense, but rather interactive elements that function similarly to power-ups by aiding progression.
- Special Keys: (All Teams) These glowing, rainbow-colored keys are found in Act 1 of each stage. Collecting one and reaching the goal allows you to access a Special Stage to earn a Chaos Emerald. They are a crucial 'item' for 100% completion.
- Lost Chao: (Team Rose) These small, blue creatures are the primary objective in many of Team Rose's stages. Collecting the required number allows you to complete the stage. They are often hidden and require Cream's flight or Big's power to reach.
- Keys (Chaotix): (Team Chaotix) Similar to Lost Chao, Team Chaotix often needs to collect a specific number of glowing green 'Keys' to complete their stages. These require Espio's stealth, Charmy's flight, or Vector's power to locate and retrieve.
- Team Power-Up (Color Spheres): (Special Stages) In Special Stages, collecting these colored spheres increases your speed and fills your Team Blast gauge, which is essential for catching the Chaos Emerald.
These team-specific elements highlight the unique objectives and playstyles of each team, encouraging players to adapt their strategies beyond just speedrunning.
