A rare yellow yeti appears as a character in the comic King Egg.

His first appearance was in "El Yeti" but he's also in "El Libro", and "El Ogro".

King Egg is by Miguel B. Núñez, and you don't need to know how to read Spanish to appreciate it.

The description of the comic (translated from Spanish) is:

"The adventures of a king without a kingdom, who came from an egg..."
