Zerimon is a Slime Digimon whose name is derived from "Jelly" (ゼリー Zerī?), and as such is green. Zerimon and Conomon are extremely rare Digimon, which are born in pairs from a single [[Digi-Egg ()|Digi-Egg]]. Why only Zerimon and Conomon are born as twins is not clearly known at the present stage. What is more, they are not restricted to always being born as twins, and either a Zerimon or Conomon may be born from a single Digi-Egg. Compared to the extremely energetic, one-horned Zerimon, the three-horned Conomon has a relatively docile personality. Also, unlike other Slime Digimon, Zerimon is perfectly firm other than just the horn on its head. Like other Fresh Digimon, it spits acid bubbles to intimidate opponents.
