Upon use, Inkling throws a pyramid shaped bomb forward that will explode and damage enemies in its radius. The distance and arc of the Bomb's trajectory is determined by the length of the button press: a short press will lob it a short distance, while a held press will toss in a lower arc for a further distance. If the bomb touches an attacker upon activation/throwing animation, then it would explode upon impact. The Bomb detonates a set time after being thrown, and will bounce off enemies and the ground while this timer ticks down. If the ink tank is below the labeled meter, Inkling will instead look down at the ink tank worriedly, vulnerable for attacks, and if it's empty, Inkling will recharge ink.
Splat Bombs are sub weapons within Splatoon and Splatoon 2. The player can use it at any point with one of the shoulder buttons, if they have enough ink. Splat Bombs (and other sub weapons) use up a set amount of ink. However, located on the Inklings' ink tank is an arrow that determines how much ink they need in order to use their sub weapon (in Splatoon 2, the arrow can also be seen in squid form via the ink tank icon); this arrow carries over into Smash Bros., as it can be seen on their ink meter and ink tank. Unlike in Smash Bros., Splat Bombs detonate a set time after touching the ground, and consume significantly more ink at roughly 70% of a full tank. This difference is shown on both the Splatoon series and the Super Smash Bros. series amiibo, with the arrow being adjusted accordingly for both series’ usage of the Splat Bomb. Like most of the Inkling's other specials, its coloration is based on its appearance in the original Splatoon.
