Make an M&M! You can change his color (COL), size (SIZ), even make him mini M&M's (MINI)! (Make mini M&M's normal again with the size button.) When you're done, you can press the M sign to send him to the world! (The sign I've only just realized looks like a mirrored Romania flag) And on Tuesday, you can press the TUES button for a surprise! (Like an actual, fun surprise. Not my normal gory surprise.)
Basically just an excuse to use the visual effects, and buy M&M's for 'research'. I really like M&M's.
