My Doll Is Lost! is a 1984 Sesame Street storybook featuring Herry Monster.

Herry receives an invitation in the mail for a tea party. The letter also instructs the invitees to bring their favorite doll. Herry skips to Betty Lou's house and discovers she has been invited too, but he realizes he has lost his doll. Betty Lou and the rest of the Sesame Street gang go off to help Herry find it, but it is Oscar the Grouch who has found it, and has been keeping it in his trash can.

The doll that Herry searches for is not Hercules, nor does Big Bird bring Radar to the tea party.
