This isn't even all of them-- I crocheted a few more piggies and a bat after I took this group picture.
Sonia loved the "army-gurumi"!
I found almost all of these crochet patterns on the internet-- FOR FREE. The internet rules. Sometimes.
I've linked where I found each of these patterns. Most of these were made with worsted-weight yarn and either an F or a G hook. I love using the shiny black plastic safety eyes-- they make amigurumis look so much more alive!
Beaver (I think this was my favorite!!)
Walrus (This one was from an amigurumi book that my friend, Joann, lent me.)
Bee (whoops, not a very good picture of it)
Alligator (This was from Joann's amigurumi book, too.)
