Egg-Rock

"It's a rock! It's an egg! It's an egg-rock!"

- Chilbo, Slusho and Dribbal respectively

The Egg-Rock (named by multiple Mixels after its shape) is a metal capsule which contains the Shadow Oracle.

Trivia

 * It is seen in sprite files of Mixels Rush grouped with Nixel-based models, possibly hinting at a villainous connection.
