"In Heaven's Animal Design Department, designers create a variety of new animals daily while contending with the unreasonable requests of their client: God. This series answers questions such as, 'Why can’t unicorns exist?', 'What makes an animal taste delicious?', 'What’s the most powerful creature in the ocean?', and, 'Bird versus snake: who would win?'"
