Crystal ball (obstacle)
From the Super Mario Wiki, the Mario encyclopedia
Crystal balls, also described as eggs, are obstacles that appear in Super Mario Land 2: 6 Golden Coins. During the first two phases with regular Wario and Bunny Wario, they appear one at a time hanging from the ceiling, moving right and left. When Wario forcefully lands on the ground, the crystal ball stops and falls directly downwards, flashing. It causes damage if it hits Mario in this state. It shatters when it hits the ground, and another crystal ball takes its place on the top-right. They do not appear during the third phase with Fiery Wario.
