Gnarantula

Gnarantulas are cloud-covered arachnids found in Mario & Luigi: Partners in Time, found in the skies or caves in Yoshi's Island. Their name is a pun on gnaw, ant and tarantula. Only Baby Mario and Baby Luigi can encounter them. The cloud hides their body; when attacked, a Gnarantula's unmasked form is revealed. In fact, there are two types of Gnarantulas: the green, spiked Gnarantula and the red, spike-less Gnarantula. The green variety is vulnerable to fire attacks, while the red variety is vulnerable to ice. To attack, a Gnarantula jumps, then jumps again in mid-air, eventually falling to the ground and crushing an opponent. This attack can be countered with a Hammer. If there are 4 Gnaratulas with no other enemies, all the Gnaratulas to the right are green and all the Gnaratulas on the left are orange.
