Collector's Edition, Roseville, [[Prima Games]], 2007, pp. 82–84, 109, 114, 163, 207, 249.</ref> '''glass domes''',<ref>Browne, p. 141.</ref> or '''glass spheres''',<ref>Browne, p. 140.</ref> are breakable objects in ''[[Super Mario Galaxy]]'' and ''[[Super Mario Galaxy 2]]''. They are hollow glass spheres held together by steel bars. They appear floating in the air or partially embedded into the ground, resembling hemispheres. Glass cases often contain items of interest, such as [[Star Bit]]s, [[1-Up Mushroom]]s, and [[Power Star]]s. In the first game, glass cases can be broken only by lured [[Bullet Bill]]s, an essential element in defeating the boss [[Megaleg]]. This remains the case in ''Super Mario Galaxy 2'', but [[Mario]] (or [[Luigi]]) can also break glass cases directly with the [[Spin Drill]]. [[Yoshi]] can hold and directly launch a Bullet Bill, [[Spiny Egg]], or [[Crabber]] claw from his mouth at glass cases. A glass case is part of the boss [[Digga-Leg]], and targets similar to glass cases are built into the exterior of [[Megahammer]].
