Hamburglar

The Hamburglar is a fictional character that was once part of the marketing campaign of McDonald's. The McDonaldland character is known for saying nothing other than "Robble robble robble." The design of the character changed from the 1970s to 1980s from a less sinister to a more cartoonish face.

Today's commercials focus mainly on the Ronald McDonald character. However, Hamburglar is still one of the core McDonaldland characters, appearing in the actual restaurants and associated merchandise.
