Upcoming DVM - Ideas for Goblin mounts? (Patreon)

Denizens of the tower, the next Dungeon Vault Magazine is called "The Scaldind Duchy".

It'll be a massive desert regional map where goblins need help restoring the right temperature fo their home.
However, goblin nomads and barbarians inhabit the desert and are a danger to travelers. We were thinking to give the goblins unique mounts.

What animal or beast do you picture goblins riding through the desret dunes?
