For as long back as Big Mac could remember, his role in life was the silent older brother that kept everything in check. After a while however that burden became too much to bear, and he needed to come up with a way to keep him sane.

...until his little orange sister poked her head in at the wrong time.

Big Macs in for an interesting ride.
