A goat that acts extremely suspicious because it follows people and isn't seen doing any tasks. It could either be the impostor, or it could be innocent... just really, REALLY suspicious.
Ryuko: What's that goat doing over there standing next to the garbage?
Mario: Ryuko, the goat isn't taking out the trash! It's acting pretty sus, so I'd say that this is a Sus Goat!
Ryuko: ...are you that obsessed with Among Us?
