Togemen

Spikeshells are creatures appearing in the Wario Land series, where they are enemies that impede Wario's progress. They look like small black creatures with white limbs, wearing a purple shell covered in spikes, and they utilize jumps to move around. The Spikeshell's only appearance up to date was in Wario Land II, although it is notable that they are near identical to the Porcupine Fish from Wario Land: Super Mario Land 3 in demeanor, and also look similar to them.

Wario Land II
Spikeshells appear in Wario Land II as common enemies. First they remain quiet, but when Wario approaches them, they begin to jump in his direction, trying to harm him. Coming in contact with their spikes will cause Wario to take damage and lose coins. To stun them, the player has to attack their weak undersides or their unprotected back. Another attack or a thrown enemy will dispose of the Spikeshell.
