Literally just copy/pasting this from another, shittier, bizarro forum:
For the uninitiated: Mister Squiggle is a fun drawing game that anyone can play. The rules are simple:
1. You begin with a 'squiggle'. This is just a random jumble of lines and shapes that the previous player has created.
2. Draw on the squiggle, connecting lines and adding shapes to form a picture.
3. While you are allowed to rotate the squiggle, do not edit or alter the squiggle itself. Just draw on it as it is.
4. When you are happy with your completed picture, post it in here.
5. If you are the first to finish a squiggle picture, then congratulations! You get to create the next squiggle for others to play with. It is recommended that you save your squiggles to .PNG format. This makes it easier for the rest of us to work on them.
...And so on. Comments are allowed, but please don't derail the thread.
But enough of that. Let's get started! See if you can finish this picture:
