Ideas - Pink Cat and Piki

I was thinking about the kind of daytime cartoons that I used to watch when I was very young, and wondered if i would be any good at creating a character that appealed to young children. Pink Cat and Piki is the story of a naughty little boy cat called Pink Cat and his best friend Piki. Pink Cat is.......a pink coloured cat who goes on many adventures . His best friend is a white marshmallow called Piki. Sometimes its hard for Pink Cat not to eat Piki because he loves marshmallows, but its his best friend and losing Piki would make him very sad.
The idea would be that the two of them would go on many fantastical adventures by leaving through a magic door in their back garden. The character designs would be very basic and made from simple shapes, almost looking like cut paper. The stories would teach kiddies about all the general values in life.
