In 1999, Midwest of Cannon Falls released two Muppet porcelain hinged trinket boxes.

On one box Miss Piggy is in a bubble bath, with one leg in the air, admiring herself in a hand mirror. A small purple shoe is inside the box.

The other box shows Kermit the Frog sitting on a log playing his banjo. The base reads "Why are there so many songs about rainbows?" There is a small rainbow inside the box.
