The creature has thick golden-brown fur, expressive round eyes, a wide flat nose, and a soft, friendly facial expression. It is wearing an official McDonald’s uniform: a dark grey short-sleeve button-up shirt with a red-and-yellow McDonald’s logo patch on the chest, dark trousers, and a navy-blue McDonald’s cap with the iconic yellow ‘M’. The creature has large, clawed hands covered in brown fur, and is handing over a classic McDonald’s brown takeaway bag with the yellow ‘M’ printed on it.\n",
