Clotty

Clotties are a category of blob-like enemies jump around the room and shoot projectiles in the cardinal directions. Revelations adds the following variants.

Frosty Clotty
Frosty Clotties are Clotty variants that spawn from Ice Hazard Blocks. They move around and shoot tears in the four cardinal directions.

Frosty I.Blob
Frosty I. Blobs are I. Blob variants that spawn from Ice Hazard Blocks. They move around and shoot tears in all eight directions. They have a very small chance to replace Frosty Clotties when they spawn upon entering a room.

Trivia

 * Frosty Clotties were added in Sin Update, and replaced Frosty I.Blobs in most room layouts.
