Fake Smash Ball
From the Super Mario Wiki
The Fake Smash Ball is an item in Super Smash Bros. Ultimate that resembles a Smash Ball, but with the lines on the Super Smash Bros. logo inverted (the horizontal line being thicker than the vertical line) as a way of deceiving players into thinking it is the real Smash Ball. It appears at a random time in the stage and can be hit similar to a regular Smash Ball; however, once it is broken, it explodes in an "X" formation and inflicts up to 43.2% damage on nearby fighters, launching them away. A Fake Smash Ball may even appear alongside a genuine Smash Ball, and unlike it, which moves arbitrarily around the stage, the Fake Smash Ball moves towards fighters, increasing their chances of accidentally breaking it.
The Fake Smash Ball may spawn with Soccer Ball physics, and begin rolling on the ground, in a matter reminiscent of the original.
