The Penguins were wandering in the wild forest looking for a door that would open to a new world where, hopefully, the lost ice-cap would be in hiding. They were quite exhausted and depressed, finding it very difficult to communicate with other beings that persisted in declining to use the new language they had created. Caymans were unhelpful and insects amazed by their nicely polished layers of black and white feathers. Eventually, one of the penguins stated that doors being yellows, as everyone was aware of, it would be easier to look for this colour in the first instance. The Penguins regained a bit of their lost enthusiasm and feverishly sought anything related to this particular colour.
