Kamoebas

Kamoebas was a rock turtle that was mutated into a monster by the alien creature known as Yog, which had been brought to Earth on a space probe and now sought to take over - starting with Sergio Island.

Information
Following the failure of its takeover of Sergio Island using the monster Gezora and later the monster Ganimes, Yog (which had survived the deaths of both monsters) decided to this time attack Sergio Island with two monsters instead of one. Taking over a rock turtle's body, the alien creature mutated the turtle into the monster Kameobas. For it's ally, Yog (impressed with Ganimes despite its failure) took over another stone crab and mutated it into another Ganimes. Together, the two monsters attacked the island and victory seemingly would soon be Yog's.

However, the humans on the island refused to give up so easily and managed to discover the monster's weakness to sonic waves. Using this information to their advantage, they released a swarm of bats - whose cries succeeded to cause Yog to lose control of both monsters. Free from their mind control and both in a 'beserk' state, Kameobas and Ganimes began to battle one another. The fight eventually leads up to the island volcano - where the two monsters (along with Yog) would meet their end as the humans detonated explosives around the volcano - causing it to erupt and kill the monsters.
