Penus is the horse Imaginashun Huntaaa found when destroying Minecraft. He went and killed, it, but when he killed it, it appeared in another place. It fought Imaginashun Huntaaa, as Imaginashun Huntaaa got beat up. He summoned his friends (Imaginashun Eater, Weed Man), but they didn't do any good. So Imaginashun Huntaaa gave up and ran away. He never saw Penus ever again. Although it is stated that Imaginashun Huntaaa named the horse "Penus"
