Trivia: In Bowser's Castle, there is a Thwomp locked behind bars, and if you bump the bars he will make a face and laugh at you. The laugh used is actually the same laugh from Wario but slightly slowed and pitched down. Rumours about this Thwomp circulated around playgrounds for years and players nicknamed him Marty. Developers even gave a nod to him in later Mario Kart games reusing the laugh. And Marty has also become the subject of several creepypastas.
