Mud is a brown-colored terrain feature exclusive to the land area that slows down most animals that come in contact with it. However, Pigs, EaglesCrocodiles, Rhinos, Dragons, Eagles, Hippos, and Black Dragons are able to swim/fly quickly through mud, but Rhino and Elephant can only move slightly faster in mud. Mushrooms often spawn in mud. Mud also slowly regenerates your water. It also spawns carrots and pears. Newly, as new as December 25, 2017, there was an update where there were eggs, which gave about thirty xp.
