Looking for Something HELP!!!!!!?

Years ago. . . .and I do mean years ago, we had some little drinking cups. They had a clear dome lid and a straw. When you drank out of them a little choo choo, or duck, or some kind of little toy would zoom around and around. It was so cute. I want one so bad for my grandson. I have searched and searched on Ebay. Does anyone know what I am talking about? Do you know where I can purchase one?
