An aquatic breed of frog-doll monster that has eyes on top of its head instead of ears. It may be related to Shignil (It puts one in the mind of Frog Hopper or Kerorin), and has soft, bedazzled skin that is waterproof.

Etymology Edit

Kero is the Japanese onomatopoeia for the sound a frog makes, much like the English word "ribbit!"
