History[]
Spiny Tromps are large, spiky and round species of Thwomps that are only found in Mount Lineland and Underwhere Road. Spiny Tromps are invincible and cannot be defeated in any way and they are too large to jump over. The only way to get by Spiny Tromps is to use Mario's Flip ability in order to get by them.
