add a legendary throwable called "Boombox":
- a super rare mole crate drop (maybe 2%? should not replace any existing spawn rates)
- max stack is 1, deals zero damage on hit making it completely harmless
- only activates once it hits the ground, cannot be picked back up once activated
- when activated, plays random sar tunes for the rest of the round (either custom made for boombox or an assortment of existing certified catbaux classics)
- the music has somewhat high range so it can be heard from offscreen (or at least the very edge)
reason:
- for casual players: very fun and rare cosmetic item
- for comp players: can be used as a distraction/deterrent, or to drown out movement sounds
