Good ol Quick Coffee is a cute thicc boi in those socks. A far off look for the non alicorn, though the appearance may convince ponies otherwise. He is just a pegasus and unicorn fusion. The combining of Soarin and Donut Joe giving us this thicc yet very physically fit stallion. The chubs are merely side effects to the mass of muscle he packs under that blubber, along with a basic skill use with magic allowing him to do much more when under pressure apart from flight. This does help the stallion when either running his coffee/donut shop of his component unicorn or when doing his back-up role for the Wonderbolts. Though it sometimes amazes some how he is able to squeeze that fat flank into a jumpsuit for practice.
 
Either way Quick has made a good routine for himself. The big lug enjoys living in Canterlot and enjoys the company around him despite the every so often confusion about his appearance by somepony new. Going along to meet with his good friend and fashion designer/entertainer Celebratory Attire. The booty thicc earth pony/unicorn stallion enjoys his company when they do meet after all, relaxing at his home and doing various things together. Whether it’s baking, games, or just good conversation they have a good time. Now that Quick Coffee has these lovely pairs of socks, he can rest his hooves after working now, allowing the thicc boi a peaceful slumber in the end.
