The tank fires a cannonball upon activation that explodes when it hits something, killing characters and knocking them off their Pet. It gives a slight speed boost. Its attack reach is outmatched by the Robo Spacecraft.
The tank is good at harass and steady pressure, using the pet into a wall will cause the shock to kill anyone in it's radius, even behind the player. Using the tank at a incline, its reach can be greater if used here. Since the tank has a slight speed boost, and is a large pet, it can grab lots of stars to prepare another tank, and can provide last second 1st place finishes. Also check out Turtle.
