Booyah Bomb

The Booyah Bomb is a special weapon in Splatoon 2.

When activated, the user holds up a glowing ball of ink that charges up over time and can be thrown to make an ink explosion, which is made larger as it charges up. The user and their teammates can use the "Booyah!" signal to charge up the special faster. Teammates using this signal will also slightly fill up their own special gauge. The charge will take approximately 8.5 seconds to reach its max power without using the "Booyah!" command. With only the user pressing the "Booyah!" command, it can be reduced to about 3 seconds, and less if multiple player's are contributing.

The user will be protected by a limited-durability shield similar to which will negate till it either breaks or when the special ends.
