Sulfur cube ideas that aren’t in minecraft preview

• Make sulfur cubes emit light when given a light-emitting block • Make them able to play music when hit while holding a note block • Make them able to take music discs and play them while holding a jukebox • More of a random idea for a variant: Potent sulfur cube, which is hostile and acts similarly to slimes or magma cubes in the way that it bounces towards you, and maybe gives nausea upon hitting you while also gaining abilities by picking up dropped blocks or nearby suitable blocks
