hehe.... the middle one looks like Bubs... <.<   >.>
Xp

yep thats the trick I use as well :P

In MS Paint: select the old color (in my case, red) as the first color (eye dropper, left click on red in image) select the new color as the second color (in my case green, right click with eyedropper on green in the image) now select the eraser, hold right (not left!!) and go over your red lines
they turn green :D

Hey looks great, and I saw your movie on youtube and just 1 little question when you made those red lines you toke a coler of Blobbo and somehow you turned the red in green but only the lines, How do you do that?

cool
very cool like it

Very simplistic, But i like it's Jelly-ish Looks, and As i type this i noticed you have shadows on it!  well done!
