The Chao Attack takes the form of Cheese, Cream's Chao, launching forward, both as an icon and on the tracks.
In gameplay, the Chao Attack can only be obtained at random from Item Boxes by Cream and Spring Cream. As with most other Items, Metal Sonic can also use the Chao Attack if he uses the Steal Item to steal it from the aforementioned users.
Once obtained, the player can utilize the Chao Attack by pressing its icon on the bottom of the HUD. When used, the user lets Cheese out, who will quickly travel down the lane they were deployed on in front of the user. After flying down the lane for a while, Cheese will then ricochet in the opposite direction. Opponents caught in the path of the Chao Attack will take damage, causing them to lose Rings and slow down momentarily. In addition, the Chao Attack can travel through obstacles and will continue moving after hitting rival characters. To avoid the Chao Attack, the playable character has to step out of its lane.
The Chao Attack can also be upgraded by leveling the user up to level 6 and 12 respectively. For each upgrade, the player will increase the damage dealt with the Chao Attack.
