Ok, I know there’s already a lot they’ve added to the oceans, but just remember how many land mobs we currently have. Jellyfish would essentially just be like moving Berry Bushes, with tentacles spanning 1-6 blocks long. They’d be passive which means that they wouldn’t attack you if you hurt them, but you could still always take damage from their tentacles. Basically, they’d just be vibing. You could even get poisoned for touching their tentacles. And maybe they could come in different varieties and colors too. When they’re killed, they’d drop Jellyfish Tentacles. Which, when brewed, could allow you to make the “Poison Touch” potion, which would enable you to poison anything you attack. This is just a really neat idea I thought of, since I really like Jellyfish :/
Jellyfish would actually be a nice addition to minecraft. It could make the ocean even more lively, and would look great in aquariums. I really like the idea of a new potion, but we already have fire aspect. Maybe it could be added to a strength potion?
