"Guinderella" 

This is a princess guinea pig.  She is made of artificial fur.  She has felt ears and feet.  Her princess hat and dress are made of shiny material.  She has clear plastic whiskers and embroidered eyes and nose.  They are black.  The fur could be different colors and the costume too, so you could collect them all.  This toy could be sold in a box that looks like a castle.  This toy is for 5-15 years old.

About the prototypes (see pictures above):  These were a lot of fun to make!  My mom had to do the sewing, but I got to decide everything, stuff them and dress them.
