A mob based on sound. (WIP)
Current Features:
- Craftable Music Discs
- Disc Sleeve (item which can hold three music discs)
- Disc Case (block which can hold five music discs or disc sleeves)
- Muffling and Echoing Ore
- Muffling and Echoing Crystals (not fully implemented and have no purpose currently)
- Crystal Bag (holds crystals - who would have guessed?)
And more to come (hopefully)
The crystals will be used to make items/blocks to make and manipulate sound and possibly later machines which use sound.
