What was the original role of McDonald’s mascot Grimace when the character debuted?

When McDonald’s mascot Grimace debuted, the character was a shake thief.

Grimace first appeared in McDonald’s advertising in 1971 as a large, purple character with four arms. In the earliest version, those arms were used to steal milkshakes, making Grimace a mischievous antagonist rather than the friendly companion audiences know today.

McDonald’s soon changed the character’s design and personality. The extra arms were removed, and Grimace was repositioned as a gentle, childlike friend of Ronald McDonald and the other McDonaldland characters. This transformation made the mascot more suitable for family-oriented advertising.

A common mix-up is to assume Grimace was always a lovable sidekick. That is true of his later identity, but not his original advertising role. The character’s redesign illustrates how McDonald’s gradually softened its fictional brand world for children and families.
