Fizzy Bomb

The Fizzy Bomb is a sub weapon in Splatoon 2. It is a Bomb-type weapon, which can be charged up by holding down the button, increasing its power. To charge it up faster, the player must also shake the controllers up and down physically, jump in-game continuously (mash ), or move around in-game quickly. When is released, the bomb is thrown. It sprays a thin ink trail behind it as it travels before exploding. Depending on how long it was charged, it may explode up to three times. The weapon was first teased at the September 2018 Nintendo Direct, along with the Kensa Collection of weapons, two new Special weapons and changes to Splatfest. The Fizzy Bomb was released in Version 4.1.0. .

Trivia

 * The weapon's name is a reference to the fizz, or the hissing sound and bubbles of gas, that cans of soda can release if opened after being shaken, similar to the weapon's charging animation. In addition, the weapon resembles a soda can, as well as an M67 hand grenade.
 * This weapon was found by data mining as early as version, functional but without a model. It had the internal codename "Piyo", which is a common placeholder name in Japanese computer programming.
 * The Fizzy Bomb is the first sub weapon to have been added post-release in the Splatoon franchise.
