Meeps are small furry animals that live beneath the ground in holes, seen in the western part of the Spielburg Valley known as Meep's Peep. They cover the holes with rocks to keep others away. When many meeps live together they form tunnels that connect with all of their holes.
Being furry creatures, they are seen in several colors, including blue and purple, with green seeming a rarity among them.
They also seem to have some knowledge of magic.
