Purple Snails

Purple Snails spawn in the end, they are unbelievable slow, small, friendly and really rare to find. They leave a redstone dust like trail behind them, which is light green and actually works like redstone. It is called snail secretion. You can replace the redstone dust in crafting recipies or redstone machines with this farmable alternative. You can lure and breed the snails with chorus fruits, which makes them teleport around when they consume it. If you kill this animal, it has a 80% chance to drop 1-3 snail secretions and a 30% chance to drop its black shell. Use it to create a snail potion. Creatures with that effect can't change their y position. They can't jump, climb or fall. They have to use pistons, slabs or stairs to get up or down.
