Rabbid Rosalina using her Kaboomer in battle

TheKaboomer isRabbid Rosalina's weapon inMario + Rabbids Sparks of Hope. It is a machine gun-like weapon designed after aSpark plushie with a pull string that fires several projectiles at one target, destroying any cover in the way, adding up for many combined hits of damage. This weapon is similar to theRumblebang inMario + Rabbids Kingdom Battle, both being weapons that fire many weak projectiles at one target, although the Kaboomer destroys cover much more easily than the Rumblebang, which either hits an enemy or misses completely.

In Rabbid Rosalina'sSkill Tree, there are upgrades that can be purchased usingSkill Prisms, such as increasing the range as well as the critical hit chance. There is an upgrade that adds more projectiles to the attack. There is also an upgrade that causes each projectile to deal 5% more damage than the previous one, dealing much more damage to an enemy.
