Free sample potion

"" was a potion saved by Stan Pines as a last ditch effort to make the Unnamed visitor pay for not buying anything.

History
Sometime before the events of "Little Gift Shop of Horrors", Stan somehow got or made the potion with the specific intent to knock out anybody who drank it.

Near episode's end, Stan, who was upset that the visitor would not buy anything, recommended him to drink the option as a last effort to get him to buy something. The visitor accepted and drank the potion, and he felt very dizzy shortly afterwards before falling unconscious.

Appearance
The liquid inside the potion is green and is kept inside a glass tube.
