Gecqua's final stage is based on the Philippine sailfin lizard, also known as the hydrosaurus as it is semiaquatic and lives around water and mangrove swamps. It has vivid blue accent scales and a sail which allows it to swim! I thought the purple eyes on Gecqua would look good as a poison-type, and I tried to balance the markings of both it and the sailfin lizard.

DEX ENTRY: Its eyes and lips drip with poison, staining its scales. It relaxes in mangrove trees, running on water in short bursts to escape danger.

This Pokemon is a larger quad lizard, with a big sailfin down its back and tail, drippy lips and eyelashes, and drippy markings. It is water and poison type. Colors are blue, off-white, purples and pinks. END ID]
