エルクロ

The pet of the Shirayuki family. A baby cape penguin that was brought back by Hayato's parents. (Apparently all legal hurdles have been cleared up regarding this.)

Seems to understand Yuri, Ruru, and Hayto's words. Has a mysterious ability to glow in seven colors when eating food.

Its round form, fluffy fur, and the ribbon on its chest are its charm point.
