"The Ugly Cheeseling"
There once was a little rubber duck who lived on the Thames with his family. Although he always felt he was a little different from his brothers and sisters....
This story basically is the same as 'The Ugly Duckling' only instead of the little duck turning into a beautiful swan...they discover he is actually a toy rubber cheese which had accidentally fallen overboard when a young child was playing with her toy kitchen on a boat.
The story ends with a happy ending and the rubber cheese saving the day and everyone living happily ever after...I unfortnately am in work and do not actually have the time to write the full story out but then again...the best stories usually come from reading between the lines.
