I haven't made a cartoon in a while, but I spent some time doing this yesterday. I know it doesn't look like it was made by Disney, but these can take a while. You wouldn't believe it but this animation has 12 frames per second. So even though it only lasts 12 seconds, that means that it includes 144 frames... it looks simple but it can take a lot of time. To make these little clips, I use a free online tool called 'Flipaclip'. It is the best and easiest tool I have found for this stuff.
Anyway this one is meant to make you smile... I hope it does :)
