Most bad ass dessert animal?

Camel Spider, they are not really spiders though.
Horned Toad, for not being a toad, and for getting so angry at things that it shoots blood out of its eyes at them. Also it's covered in spikes.
Dessert Animal? Chocolate Moose, eh.

Now if you were talking about creatures from deserts, then I'd have to think about it for a bit because I don't usually think of those critters.
Dessert? I'd have to go with animal crackers.

Desert? Shai-hulud.
Animal cookies, of course!

But for desert animal... Pumas!
Ooooo, dessert animals! I love me some chocolate turtles.
