Dr. McSlug has his doctorate in “PetMed” as was visible in “How to: Make a glowy eye puppet”. Which makes his full name: “Dr. PetMed Jack McSlug”. He always wears a reflector on one of his feelers.

The character came out of nowhere and was conceived as a supporting role for the “glowy eye” skit. Originally the only reason he even has a name was that the script called for a “name plate” to be visible in front of him while talking to the cat.

He is based on the Folkmanis slug puppet and hs reflector is made out of a tiny flashlight reflector glued to a velcro tape.
