What a mysterious Snuggie club...

Q: Do MASCOTS have or take courses in Universities?
A: Those are specialized schools and there are a few number of them in existence. Even then, most of them only teach rudimentary basics. Usually, most undergo a private study/mentorship program with or without a third-party involved. The profession is kind of like morticians, if that makes sense.

A bit of passing the blame and lo . . . a disclosure no one counted on!
