Snakes and Sounds is a datapack that adds in snakes and musical instruments to your game! If you drop an emerald right next to a wandering trader, he will play a song for you for 30 seconds. Every 5 seconds 2 notes will randomly spawn in with a short despawn time. Collect these notes, they will be useful. Once he is done, that wandering trader will not play again. In the crafting table place a note in the center and surround it with planks you will get a musical box. It is a lucky block that will drop music disc, note blocks, jukeboxes, and musical instruments. Right click an instrument for it to play a note. It will give all entities(including you) within 3 blocks of you weakness, and it will decrease villager trade prices.

Snakes will spawn in plains, forests, extreme hills, taiga, swamps, birch forests, jungles, cold taiga, mega taiga, roofed forests, deserts and savanna. If it spawns in a desert t will be yellow, otherwise green. Snakes are neutral mobs, with 12 health. If you hurt them, they will attack you and will poison you(unless on easy mode). If you kill them the have a chance to drop scales(same use as leather), snake eyes(same use as spider eyes), bones, and a snake tail. Right click the snake tail (min use one per second) to shoot out a snake tail. It gives all mobs it hits slowness for a second.
