+## 0179 Mareep–0181 Ampharos
+
+Mareep and its evolutions are characterized by wool atop “rubbery,
+ electricity‐resistant skin”.
+In fact, wool and rubber are subject to the triboelectric effect,
+ whereby the electrons from the wool are lost to the rubber, giving
+ the former a positive static charge (explaining Mareep’s abilities,
+ Static and Plus) and the latter a negative static charge.
+This negative charge (i·e, the electrons) is absorbed by the Mareep,
+ leaving the positive charge to be dispelled by the environment.
+
+Antistatic sprays can help Mareep’s wool dispel its charge faster; this
+ is not harmful to the Mareep so long as it does not interfere with
+ the electron collection occurring on its skin.
+In fact, such sprays may boost growth by ensuring Mareep’s wool is able
+ to replenish its electrons with greater speed.
+
+Ampharos lacks any wool (unless mega‐evolved) and must collect
+ electricity from the environment directly.
+
+## 0453 Croagunk–0454 Toxicroak
+
+Croagunk stores and secretes poison from the sacs on its cheeks and in
+ the middle fingers of its hands.
+This poison is collected from the environment through Croagunk’s
+ diet—in domesticity, the poison is typically mild and safe.
+Croagunk poison acts on nerve cells and, under heavy dilution, can be
+ used medicinally as a muscle relaxant.
+Domestic Croagunk are trained as masseuses with a carefully monitored
+ diet to maximize the medicinal effect.
