Amanda, sorry this has taken me sooo long to post. I made these cute little guys last Christmas. I found this tutorial for the elephant and this tutorial the giraffe on makeitandloveit. I then made a whale and seahorse pattern (printed off a silhouette, traced it onto fabric, etc.), and put them together the same way as the elephant and giraffe. The seahorse was a little more tricky because that skinny little tail is hard to get batting into. Make sure if you do it, you make it big enough to stuff. Have fun!
