Grimace with his aunts Millie and Tillie.

Aunt Millie and Tillie are Grimace's aunts who make their only appearance in a 1999 McDonaldland commercial.

They arrive at their nephew's picnic as soon as the former tells Ronald McDonald, Birdie, and Hamburglar they were coming. Ronald initially mistakes Grimace wording for actual ants, but then he sees them coming over and they join in with the group to have some McDonald's.
