These are really nifty!
They come from a really neat site called
Blue Mountain Arts' Electronic Greeting Cards
which is worth checking out!
They've got funny animated greeting cards that you can email to folks!
(This one is by talented artist, Karen Lyn Morse, and comes from the Birthday section, under 'Froget' Everything Else And Celebrate )
Here's a couple more anonymous froggies. Please let me know if you know who created them so that I can post credits!
