ToonDoo is another site I have been playing with. It allows you to make cartoons which can be saved at the ToonDoo site and then can also be linked to your own blog. But I have had trouble finding the code to embed.
I found an interesting site with some info on embedding and other educational exercises but the code still does not appear. I am not sure if that is because I am using a mac computer. I'll try later on a PC and see if I can find it.
Here is a link that I have copied and am trying.
If I can't find the code I'll at least take a screen shot and put that in. It works, sort of, but I am not happy with it. I will persevere and see if I can come up with something better.
