Memoca is easily the most energetic of Wadanohara's familiars. She tends to speak her mind, even when it's not appropriate, such as when she goes as far as to ridicule Uomihime. She commonly has a mischievous attitude, evident when she teases Dolpi to tears and harasses Lobco by throwing slugs at her.
