As a last minute Christmas gift for some nephews I made these beanbags: a shark for a 3 year old boy and a killer whale for a 1 year old boy and an extra killer whale for my kids since I had just that much of that fabric left.
They are pretty good sized. Probably about 10" long, a fun size to play with. I make them with an extra layer of batting for padding and poly pellets. I love poly pellets because it makes bean bags that are childproof -- washable and suckable. Don't know about other people's children, but my children like to put the corners of beanbags (and other such toys) in their mouths and suck on them. You obviously don't want them eating poly pellets, but it allows the beanbags to be able to get wet without worry.
Also, they are sitting on a big tv pillow that I covered with super soft fuzzy fabric for another nephew.
