McDonald's released a set of four Muppet Babies Happy Meal toys (plus two "Under Three" toys) in 1987.
The main set had the Babies riding wheeled vehicles. The figures and vehicles were removable.
- Baby Kermit on a skateboard
- Baby Piggy in a pink car
- Baby Gonzo riding a green Big Wheel tricycle
- Baby Fozzie on a yellow hobbyhorse on wheels
In Canada, Baby Animal in a red wagon was added to the set. Some of other figures were sculpted differently: for example, the American Baby Gonzo wore shoes whereas the Canadian Baby Gonzo was barefooted.
The "Under Three" toys were one-piece PVC toys. McDonald's often makes special toys for young children when the main toys include pieces that could be swallowed.
- Under Three Toy: Baby Kermit on roller skates
- Under Three Toy: Baby Piggy on roller skates
There were four Happy Meal Boxes released with this set. Each box corresponded to the toy for that week. i.e. there was a box for Kermit, Piggy, Fozzie, and Gonzo. Tray liners were printed with a "Grand Prix" game which could be played with the PVC figures and a dice.
Among the P.O.P items (Point of Purchase items, meant to draw attention to the promotion) there was an Employee Button featuring Kermit (was rectangular with a heart), a register topper, a display featuring the four premiums, translights (illuminated plastic sheets featured on the menu board), and a dangler that hung from the ceiling featuring the toys.
McDonald's made a second set of Muppet Babies toys in 1990.
