The Case of the Missing Duckie is a 1980 Sesame Street storybook featuring Ernie and Sherlock Hemlock.

It's Ernie's birthday, and he decides to do all his favorite things. First up is a bath with his Rubber Duckie. Just as he is about to get into the tub, the telephone rings. He answers it, and Big Bird asks if he'll be home around 2 o'clock. When Ernie says yes, he hangs up, much to Ernie's confusion. When Ernie returns to the bathroom, his Rubber Duckie is missing!

Ernie returns to the telephone and quickly calls Sherlock Hemlock for help. The unfortunate detective finds every rubber item in the apartment, while Ernie takes a bath and gets dressed. Sherlock Hemlock then finds evidence of a pink and yellow monster in the kitchen and decides to hide.

At 2 o'clock, the doorbell rings. It is all of Ernie's friends, and they have brought balloons and decorations to have a party for him. Ernie is still sad that his Rubber Duckie is missing. Cookie Monster brings a big decorated cake out of the kitchen, with Rubber Duckie sitting right on top! He explains that he borrowed the duckie to decorate the cake.

A triumphant Sherlock Hemlock declares that he has solved "The Case of the Missing Duckie"!
