Unlike many other Carbink fusions, Quagbink lacks the ability to float in open air. They fare better in freshwater lakes, eating microbes and occasionally small fish and bug Pokémon.
Born from the high temperatures and pressures deep underground, it defends itself by firing beams from the jewel part of its body. A Quagbink hunts by leaving its mouth wide open in water and waiting for its prey to blunder in.
