Tianlu (天禄) is the official name for a character commonly known as Pipi (皮皮) from the Youshouyan manhua/anime series. He represents the male category of a species of Chinese mythical beasts known as pixiu, and draws parallels in the story by consuming treasure at every given chance.

The source material dictates that treasures eaten by Tianlu don't get digested, but never usually come back out either, and thus Tianlu canonically lacks an anus.
