Caricature theme - sliding down the rainbow

Looking at the client's brief:-
She wanted a rainbow, mushrooms, strawberries, a cow, and a bear.

First picture to appear in my mind is:-
It is a cute picture like those Hello Kitty, Kalm's, Forever Friends etc.
Thus, I have them sliding down the rainbow.
Gave them short body and legs, bigger shoes, and the sweet and bright colours like pink, yellow and red.
