|Functionality||Keeps skeletons working|
Growlspeakers are a certain type of speaker used by Skeleton to keep themselves working. At Sensei Wu's behest, if you smash one, you can rebuild it into an old gramophone playing the oldies. Skeletons love the oldies, and they all start dancing and occasionally spinning whilst dancing. This causes for easy kills using Spinjitzu.
- The music Growlspeakers normally play is bass thumping music.
