Your combo does not reset when you run into enemies and hazards.
— Description, Sonic Dash 2: Sonic Boom
In gameplay, Protected Combo is the Special Power of Sticks the Badger. Should Sticks take damage from running into enemies or damage-inducing obstacles, her combo chain will not reset, which it would otherwise do for other characters in the same situation. However, it does not preserve combos if the player choses to revive Sticks after she is forced to a stop.
