Anyone planning on visiting central Japan in the near future may end up seeing something totally unexpected: green polar bears.

These polar bears at Higashiyama Zoo and Botanical Gardens have been frightening visitors recently with the greenish tint to their fur, even to the point of some asking if they were carrying mold. The zookeepers assure that although the occurrence is odd, it is not dangerous. The above-average temperatures for the past two months, coupled with less-frequent water draining in the exhibit, has led to an uprise in algae growth. Algae is difficult to wash out of bears' fur, due to certain properties of the coat.

The bears are supposed to turn white in time for winter. Tragic.
