Rocket Firecracker (or Rocket Firework) is an S-grade Pet that protects cookies from falling. If the cookie fell, the rocket will save the cookie and blast throughout the stage before recharging itself to help the cookie again. In contrast to Ginger Ghost, the number of saves is unlimited, but comes at a cost of having a cooldown period.
This Pet has been used to complete "saves from falling" achievements several times, since it can help the cookie back up as much as the player wants.
Made from cherry candy and bubble gum, it flies far and bursts with joy. Its star candy powder filling helps Chewy Rocket put itself on fire and explode after a speedy flight. It can save the Cookie again when the filling regenerates.
