The Tremarctos Cumulogenitus (or Cloud Bear) is quite an unusual animal. Its unique combination of ultra-light bones and helium for blood allow for indefinite heights to be reached by this bear, although it cannot control what height it reaches.
        Groups of these bears usually cling together for warmth, similar to penguins, as the high altitudes of its habitat contain low temperatures. They achieve this grip through their velcro-like fur, which they attatch to others of the same species.
        They are carnivorous, but fairly passive, as they will only eat birds (and sometimes humans) that venture too close to their groups, known as 'clouds'.
        They are fairly small, compared to other bears, reaching only 1.2 metres tall when standing up, but they usually form extremely large 'clouds' in the sky, as they are very common.
