I have made several of these for craft bazaars. Use the instructions for the Frog given then use different colors of yarn, felt, googly eyes, and pom-poms to make the Penguin, Reindeer, Polar Bear, and Brown Bear from my pic below. (I use different sized pom-poms for most details because it's easier than cutting a bunch of felt).
I purchased one that was a bunny rabbit for easter. They cut two long ears out of the plastice canvas and stiched them up with white... was really really cute! They seemd more 2 d than krafty moms...
