Since accepting the cast of Balie, these roosters take revenge on human species for serving their ancestors up on dinner plates for generations.


Baby seal that live in the snowy fields of Shiltz. They hatch from eggs and live on snow flowers.
Qs usually lay about 100~200 eggs, but only a few actually hatch and have a chance of life due to humans hunting them down for their tender meat and delicate taste.


Weakest bale in the world of Shiltz.
Cursed to have its head turn into that of a chicken.

Afro Tree

Bale created by Balie from a tree. It is conscious of his afro.
It may not look violent, but watch its temper explode if you ever touch its hair.

but once they become mad… one should avoid all confrontation. You won't think it's cute anymore!

Papa Bear

Angry Papa Bear that supports the family by catching salmon.
His rage with Mama Bear might target you as his next victim.

Moo Moo

Can you be any sillier? The silly Balie decided to turn an innocent radish into a bale.
Being the music loving radish that it is, even its morphed being wears a headset.

Bah Bah

These Bah Bahs happily roam the snowy fields of Shiltz.
Their jolly swagger gave them the name Happy Bah Bah.
