How to Quickly Make a Marseymon using GIMP. (I need to stop neglecting my five children, so it's up to you to make the other 900.)

All you need is GIMP and some MS Paint skills. It took me twice as long to type up this post as it did to actual make the emoji.

1. Find a base image with solid line art, and paste that image onto a white background.

2. In GIMP, choose "Colors→Threshold" from the menu, and adjust the slider until you've got a nice outline. Hit OK.

3. If you want the outline to be thicker. Use the Select by Color Tool, select the Black, use "Select→Grow" in the menu, and refill your selection with black.

4. Select by Color, targeting the white this time. Hit delete. (If it doesn't vanish, make sure the layer has an alpha channel.) I also like to change the outline so it isn't pure black.

5. Now you've basically got a coloring book. Fill it in with the paint bucket tool, MS Paint style.

6. To add shading, orange spots, etc., without coloring outside the lines: Use the Select by Color Tool, click on some color, then switch to the pencil tool and scribble away.

7. Add drama.

8. Once you're done, add the white outline:

1) Make sure the canvas is big enough to have the extra room for the outline.

2) Once you've finished the image and combined it into a single layer, right click on the combined layer and choose "alpha to selection".

3) In the menu, choose "Select→grow", and choose how many pixels you want the border to be.

4) Make a new layer and fill your selection with white. Put that layer on the bottom.
