The Roadrunner is an Assist Trophy in All Star Smashers. When summoned, he runs away from the stage damaging anyone in front of him as he leaves behind a trail of dust clouds. Standing on the clouds will not only cause you to slowly sink through them but attempting an inputted ground attack will result in the respective aerial attack. As a result, should a character with a stall-then-fall Down Aerial attempt a Down Tilt on a cloud covering a surface directly blocking the downwards blast zone, they will instead perform their Down Aerial, likely self-destructing themselves.

This is based on a scene in Looney Tunes when Wile E. Coyote notices he is no longer standing on solid ground in the middle of his chase with the Roadrunner. However he doesn't fall until he sees the abyss underneath his feet.
