Apart from the dog, Toto, one might argue there is a character who is seen as a sort of combination doorman/security guard at the Wizard"s palace. This is not the Wizard himself, but another character. He wore a costume that at first glance resembled that of a Bishop, not a Police or security man. The Hat was like a Mitre and the uniform coat was Green. At first viewing I thought it was St. Patrick as he is popularily represented. ( Patrick was first Bishop of Ireland) Green costume, natch. Maybe this is the character you mean. He does no have a name or cast credits.

As far as I know there is no character named Sammy, not even the personification of Uncle Sam- fourth of July Man- in Wizard of Oz. If there is no character, logically there would be no song about him.
