Wikipedia:Articles for deletion/List of fictional penguins
Most entries are linked to Wikipedia articles and those articles have references (as with many lists), so I don't think the list requires additional references of its own for every entry (unless perhaps the linked-to article doesn't actually mention the penguin in question). I know  is not usually a strong Keep argument, but there is a pretty big precedent in the shape of a whole load of similar lists - eg List of fictional dogs|dogs, List of fictional ducks|ducks, List of fictional dinosaurs|dinosaurs, List of fictional hares and rabbits|rabbits, List of fictional raccoons|raccoons, List of fictional weasels|weasels, List of fictional worms|worms, List of fictional wolves|wolves (and that's just checking three letters of the alphabet
