Spinies are werid little spike things. They seem to be some sort of Red Koopa. Anyways, these things were on Mario's nerves when he was plumbing. They tried to knock him into the urine. (Eww...) Mario plumbed THEM into urine, which has led into groutesqe mutations. They turned into bidepal Koopa things, and grew twice as large. And they spat fire. Mario ran away like a scardey cat. The Spiney followed him, but half of them were killed by Hax at the last second.
