The four glasses include:
- Kermit on a bicycle
- Miss Piggy on a motorcycle, crashing through a stained glass window
- Kermit, Fozzie and Gonzo in a hot air balloon
- The Muppets on the Happiness Hotel bus
There was also a promotional glass produced that was available only to the managers of McDonald's which promoted the commemorative glasses.
A study funded by the Massachusetts Legislature Health Care Committee found that McDonald's glasses did not meet the state's safety standards, and specifically cited the paint used on the Muppet glasses, manufactured by Libby's Glass Company, contained more than 50% lead.
