The Humped Crab-Eating Raccoon

My future creature is called The Humped Crab-Eating Raccoon. In the future, the rainforest will become a savannah, so I've created a creature to thrive there. Like a camel, my creature will have a hump. This way, it can go several months without drinking water. It will have opposable thumbs to grab food better, and dark brown eye patch and stripes to camouflage. Its coat will be green, since my creature will live in the few trees that are there. It will live in the trees because their food, crabs, also live there.
