Gero Gero Gun
ItemA frog-styled flintlock customized for Miss Father's Day. Round-bodied with a frog's-head muzzle, it fires amphibian-shaped rounds that burst on contact, and it powers a paired attack she shares with Mr. 7.
Overview
The Gero Gero Gun is a flintlock that Miss Father's Day of Baroque Works has personalized to suit her motif. Its design leans heavily into a frog theme: the barrel ends in a frog's head, the main body mimics a frog's rounded shape, and the whole piece carries a plump, bulbous silhouette. The name itself echoes a frog's croak.
Function
Mechanically it shoots like an ordinary flintlock, but its owner loads it with rounds molded into frog heads that explode when they strike. This lets her deal blast damage rather than simple puncture wounds.
Notable Users
Miss Father's Day is the gun's owner and uses it alongside her partner. Their combined technique, Lady Smash, has both agents fire at once so the two shots meet and detonate right in front of the target. They turned it on Vivi and Chopper during their fight.
