Red Text
I'm a hot little potato right now.

This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.

A Torg-made novelty assault rifle that fires exploding potatoes rapidly. Functions as essentially a fully automatic grenade launcher, scattering splash damage. Base damage is modest, but it holds the potential to become powerful when paired with splash-enhancing builds, a romantic weapon.

🧩 Source of the red text “I’m a hot little potato right now.” is said to be a quote from the movie ‘Zoolander (2001)’ (Fandom). The phrase “hot potato” is used to describe a Heating Up and being the center of attention, which also creates a double meaning with the weapon name that fires exploding potatoes (Potato Thrower).
