It would make sense that Dr Whale is the whale from Pinnochio. We have seen Geppetto, Jiminy, the blue fairy who are all from that story. Dr Whale is the only other character from the first five episodes who do not have a Fairy Tale Land name and there is an upcoming episode concerning Pinnochio. Besides how many other fairy tales can you name with whale in it,; Disney, Grimm or Hans Christian Anderson???
