I have some work to do today but maybe tomorrow evening after I get home from class.
You recieve a Sinister Scarf as a recipe. To recieve the recipe you must win SMEB 4 times, it doesn't need to be in a row, just 4 times. BUT for your win to count you must go through the dialogue boxes at the end of every win of smeb. To do this you are sent to the barton bar at the end of every win, I suggest for people to go up the stairs there and all the way to the right or left so they don't accidentally exit the bar.
A series of dialogue boxes will appear, you must click Ok for every box that comes up. If you exit out of the dialogue boxes you will become glitched and unable to win a scarf at all on the your current account. Once you do a dialogue box you will recieve a recipe, which recipe depends on what win it is.
First win: a ring and crystal fluff recipe
Second win: null fluff recipe
Third win: mecha lab recipe
Fourth win: sinister scarf recipe
You then craft the scarf and voila~
