"Spore yourself a tall, frosty one!"
A neon sign for Spore beer is on the wall of Singent Flembuckit's room at the Dew Beam Inn. It is likely a popular beer, as the Narrator describes it as "Groovy". The description uses a slang term for "cool" more commonly associated with the sixties. Mushrooms are commonly associated with the psychedelic era, which span the sixties and seventies.
