Blobs are environmental effects in Remixed Dungeon that spread across the dungeon floor, affecting characters and objects that come into contact with them. They are dynamic fields that can expand, contract, and interact with entities in various ways.
Blobs are implemented as subclasses of the `Blob` base class. Each blob type has unique properties, behaviors, and effects on characters. Blobs can be created by mobs, items, traps, or level features.
