Grimace is a character featured in McDonaldland commercials. Now known as Ronald McDonald’s best friend, he was introduced as a villainous character called Evil Grimace who stole people's shakes. But he quickly morphed into someone known for sharing the joy of shakes with his friends. Toward that end, he is occasionally portrayed as having birthday parties involving several McDonaldland characters, including those attending Grimace's Birthday in 2023.
