This is a full set of the McDonald's Mac Band from Happy Meals. Happy Meal toys from Europe and Japan are quite similar. I had a hard time getting the full set in America because they were rare items. Here's an introduction to each character's gimmick: Birdie: Her body sways from side to side, and her mouth also opens and closes. Ronald McDonald: His waist moves from side to side, and sometimes he lifts his guitar. Because of the spring mechanism, he sometimes spins 360 degrees without you noticing. Hamburglar: Both hands move up and down, hitting the hamburger-shaped drum, and at the same time, his hat secretly moves up and down. Grimace: He moves forward while his saxophone goes up and down. All of them can have sluggish movements or stop midway depending on how tightly the spring is wound. They require a Showa-era fix, like tapping them a bit to get them going again. Even so, Ronald McDonald sitting and playing guitar, a picture of Ronald on the bass drum... Grimace just looks like he'd be good at the saxophone based on his build, and Birdie as the vocalist... it's a smile-for-free, priceless, and fun-looking band. As a bonus, this set comes with a deadstock paper box for Happy Meals. Thank you for viewing.
