The Wrench Rush's icon takes the form of a regular-looking metallic gray adjustable wrench. In gameplay, this power-up becomes a white aura around the user, which has four gray adjustable wrenches circling around it.
Once obtained, the player can utilize the Wrench Rush by pressing its icon on the bottom of the HUD. When used, the Wrench Rush will increase the speed of the user for a short amount of time. The duration of the Wrench Rush is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Wrench Rush is in effect. In addition, any rival character who gets too close to the user (even when they are on adjacent lanes) while Wrench Rush is active will take damage, causing them to lose Rings and slow down momentarily.
The Wrench Rush can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the speed of the Wrench Rush's speed boost will increase.
