Seal

Seal (name unknown) is a Shinheuh that appears on the 25th Floor of the Tower.

About
The Shinheuh appears just like a real-life seal. It has black, round eyes and skin color that varies between black and dark blue. As it is able to swim in the sea of clouds and is big enough for people to ride it, the seal is used as a taxi service in the 25th Floor with the rider being on the front seat using a dumpling-like bait to control the seal. Based on the writings on the back of one of the seals, it can be assumed that the seal is fast enough in transporting people.
