McDonald's released a set of four Muppet Treasure Island Happy Meal toys (plus an "Under Three toy" for younger children) in 1996.

The set had four floating bath toys:

• Kermit as Captain Smollett, in a pirate ship. The cannon on the front squirted water.
• Miss Piggy as Benjamina Gunn, relaxing in a boat.
• Fozzie Bear as Squire Trelawney, floating in a barrel. Fozzie's head could be pushed up and down in the barrel.
• Gonzo in a boat with a paddle wheel at the bottom. When you push down on the stack of gold in the back of the boat, the paddle wheel spins.

The set also included an "Under Three toy" -- a four page bath book. McDonald's often makes special toys for young children when the main toys include pieces that could be swallowed.
