The Penguins were running in all directions. The wild green nature around them was slowly becoming suffocating. None of the shortlisted yellow animals they had previously identified had a clue where a door could be found. They had no other choice than looking for a yellow butterfly – since according to common knowledge, at least in their extended family, had a good and sound knowledge of doors, toasters, daisies, vacuum cleaners and turtles. By pure chance, they found one whose name was Robert and they started exchanging thoughts, jokes and old says with him. He eventually told them that if a door was to be found it would be near an exit, a confession which mesmerized them profoundly but only after having had an incredibly nice and sweet dinner and before taking a good night sleep… They all believed that they were getting closer than ever to a breakthrough in their quest.
