#179 Mareep - Its fluffy coat of wool rubs together and builds a static charge. The wool increases in volume when it builds up with electricity, and the bulb at the end of Mareep’s tail glows brighter the more electricity it has. Touching the wool when it is charged will result in a nasty static shock. In the summer, the fleece is fully shed, but it grows back in a week. Mareep also stores air in its soft fur, allowing it to stay cool in summer and warm in winter.
