Hidden Blooks

Hidden Blooks is an area, pack, or collection of blooks found at the end of all packs on the Blooks Collection page. This section contains some of the rarest blooks in the game that are added when you obtain them. These include Chroma, Unique, Mystical, and Unreleased blooks (when you use hacks). You can also view retired blooks here if you have collected any of them.

The blooks in the Hidden Blooks section are usually very rare, such as Mysticals, and are mostly obtained through seasonal packs like Chroma Blooks, special events like Contest of Candies, or other unique methods. The easiest blook to get in this section is the Wise Caterpillar, which can be added to your collection with just one click.

All Mystical Blooks appear in the Hidden Blooks section once you obtain them.
