Zerimon

Zerimon (ゼリモン)
An extremely rare Digimon, which is born in pairs from a single Digitama. The reason why only Zerimon and Cocomon are born as twins is unclear at the present stage. Moreover, they are not restricted to always being born as twins, and either a Zerimon or Cocomon may be born from a single Digitama. Compared to the extremely energetic, one-horned Zerimon, the three-horned Cocomon has a relatively docile personality. In addition, unlike other Slime Digimon, more of Zerimon than just the horn on its head is firm-knit and rigid. Like other Baby Digimon, it spits acid bubbles to intimidate opponents.

Etymology
Zeri: A romanization of ゼリ, translating to jelly.
