After a successful attack against an enemy cat, there is a certain chance that a gas grenade will fall on the ground. This grenade instantly explodes, neutralizing all enemy cats in the yard. The function is unlocked from the start of the game.
For each cat killed by a grenade, there is an instant reward equal to the multiplier. The keys to unlock the next farm level are collected automatically.
A grenade will appear when the feature is 100% charged. Each successful attack against a cat will charge this function by a certain percentage.
After the grenade detonates, the recharge level of this function starts at 0% again. Grenades will only spawn if there is at least one cat in the enemy yard.
