DuCair Bioessence produced two floating Muppet soap dishes. They were designed to hold mini-soap bars.
1988 soap dish[]
The 1988 soap dish was made in the shape of a plastic toy car driven by Kermit the Frog, with Miss Piggy as a passenger behind him. The "trunk" of the car held decorative soaps. While Kermit is driving, the pink car clearly belongs to Miss Piggy -- it's decorated with hearts, and the license plate is a cursive "Kissy".
1991 soap dish[]
The 1991 soap dish pictures Miss Piggy in workout clothes, lounging on an exercise mat. It was released under the Kid Care label.
