Smiley was Caesar Clown's pet and the weapon he used to destroy Punk Hazard four years ago. Caesar created it by giving a Zoan Devil Fruit to the H2S gas.
Smiley died after getting free from Punk Hazard's shelter by Caesar's command. It ate a massive candy that produced a chemical reaction in its body and turned it into the Shi no Kuni gas.
