A Spiky Tromp is an enemy in Super Paper Mario.
In Super Paper Mario[]
Spiky Tromps are Thwomp-related creatures that are mainly seen in Yold Ruins (Chapter 1-4). Spiky Tromps commonly roll around damaging anything that gets too close to them. A horde of Spiky Tromps actually help Mario and Tippi cross a large room of Yold Ruins. Spiky Tromps have a subspecies called the Spiny Tromps.
They have a huge resemblance to a Grrrol from New Super Mario Bros. U.
