Controlled and powered by the malevolent intelligence of the Amoeba being, a gigantic stone crab, Ganimes, attacked the island. Trying to finish the job that the now dead Gezora left undone, the monstrous animal wadded further inland, before it was met with machine gun fire. However, this does little to detour the creature. Yet the humans once again managed to outsmart the bulbous monster by luring it into a pit, laced with hundreds of sticks of dynamite. The resulting explosion tore his body apart, leaving smoldering bits of flesh. However, the spiritual Amoeba was still alive, and crawled from the open carcass only to assimilate another stone crab.

This duplicate Ganimes was sent to aid another infected animal, this time a jungle turtle named Kamoebas, to eliminate the human threat. Though the partnership was soon dissolved, when a horde of bats besieged the twin giants. The supersonic waves created from their cackling cries broke the hold that the Amoeba possessed, and drove the monsters to fight. Ganimes attacks relentlessly with its pinching claws, and spiting foams of blinding, coalesced seawater, but Kamoebas was able to hold its ground. So caught up were the monsters in their war, that they didn't notice the volcano that they fought on. So, they both proceeded to the lip of the mountain, and toppled inside. Killing themselves and the Amoeba beings that laid within.
