Spiny Shroopa

The Spiny Shroopa is the Shroob version of the Spiny. A Spiny Shroopa has a purple shell with pink spikes. Unlike Spinies, Spiny Shroopas stand on their hind legs. Additionally, small, gray arms stick out the front of a Spiny Shroopa's shell. A Spiny Shroopa's head stays inside its shell; as such, only its glowing yellow eyes remain visible. To move, Spiny Shroopas do not walk (like Spinies). Using their powerful hind legs, Spiny Shroopas hop like frogs to move from place to place.

During the Shroob invasion of the Mushroom Kingdom, Spiny Shroopas were ordered to protect the Vim Factory. Upon seeing an intruder, Spiny Shroopas would rush to attack. In battle, a Spiny Shroopa attacks by charging at an opponent. To counter-attack, Baby Mario and Baby Luigi should hit the Spiny Shroopa with their Hammers as the monster approaches. Sometimes, a Spiny Shroopa's charge attack can poison a Mario brother if it is not countered.
