Haha, Goomba rip offs go brrrrrr- So my reasoning for this is like... You know how Aliens exist in Mario? Yea, that's just gonna be like a bunch of Goombas to eventually be sent into a whole new world. Like what happened with Sonic and Mario. Sonic and Mario characters went to the real world to compete. Also, SSBU is a thing, so... Yea. Anyways, enjoy their idles.
