This camel is easily the size of a giraffe. Its limbs and neck are stretched out like a giraffe's but it is otherwise built like a camel, complete with a small hump.
The giant camel is a larger cousin of the modern camel, though it lives in grasslands rather than deserts.
Combat
Like a modern camel, giant camels will spit if they feel threatened. If forced into a physical confrontation, giant camels will bite and kick their attacker.
