And remember, look for the Hovercrocs throughout Steamport City. The Hovercrocs out in the hazelands are too hardy and don't seem to drop any remains.
I hear the teeth may be left behind when they combust, so if you could collect 25 of these it would help my research a great deal.
I hear you've encountered Hovercrocs out in the hazelands while Trailblazing. For some reason, a few of these creatures have ventured out of the hazelands and into Steamport City. I'd love to study them while we have the chance, so would you mind helping out?
