The magical and totally unicorn cat of Brittany S. Pierce on Glee. Lord Tubbington only eats people food, nougat and glitter so he can poop candy bars, and at night (when he's not reading Brittany's diary) he sneaks off to smoke and get Arby's.
Brittany: Lord Tubbington got out and I found him at Arby's, how did you get into my room?
Rory the Leprechaun: Santana has just one wish - she wants you to quit Glee Club.
Brittany: Great - why couldn't she have just wished for Lord Tubbington to stop smoking?
