I read this comic book as a child, but can't recall its name and Google couldn't help. It's about a boy and lots of animals. As far as I can remember the boy regularly enters a dream-world, where he encounters a lot of different animals (can't remember what exactly he was doing there). His mother gives him a goldfish, which he names Moby Dick. This fish also enters the dream world.
In my version the first two pages of the book contained a huge picture of different animals (whale, penguin & others).I read it in German, not sure if this was the original language or a translation. Anybody know what I'm looking for?
