The Aquarang is first seen in Ty the Tasmanian Tiger in the level, Ship Rex. When Rex teaches you how to swim, he also gives you these special boomerangs. They were found in a shipwreck long ago and "can cut through water like a hot knife through butter." They seem to resemble boomerangs but look more like green fins. In the next two games however it appears as a regular boomerang even though the game refers to it as the Aquarang.
