Monster who hit the jackpot

Monster whose nickname is "Reckless". Yes. With an R. Not a W. No matter what you might have heard.

Monster who remembers all those that will never grow old, lest they forget

Monster who's here to open doors, whether they want to be opened or not

Monster who hasn't been on a date in... oh. Oh dear.

Haunting the place? Excuse you, this monster is bringing a priceless ambience with them

Monster who wants out

Monster who's decided they'll follow you to the ends of the Earth

Monster who thinks it's time to hibernate. Wake them when the ice age is over.

Monster who sometimes reverts back to the first language they learned
