Make a tabletop roleplaying game about or featuring the Fossa--which is kinda like a cat--that lives on Madagascar. Maybe you'll write an adventure, monster write up or character type for an existing game; or make a setting, scenario or game of some sort that is either system neutral or unique.
Bonus points for featuring fossa-puns in your title and/or game.

(please note: yes, this is a slightly silly jam focus, but that doesn't mean your submission needs to be or should be.)
