Jellyfish mob recommendation and why I think they should be added in game.

Hello, I am here to propose the idea of a jellyfish mob. Here's why I think jellyfish should be in game. For starters, currently jellyfish are extremely popular, so I think they could easily catch someone's attention. Secondly, I feel Minecraft is lacking aquatic mobs. Third of all, I think anything they drop after being killed, for example like a tentacle, could be used to make potions, considering the fact in real life jellyfish stings can result in sharp stinging pain, redness at the area, Itchy sensation, swell on affected skin areas, feelings of nausea, headaches, muscular pain, respiratory difficulty, heart dysfunction, weakness, and drowsiness. I believe all of the symptoms I just listen could correlate well with different potions of sorts. I also think, if they were in game, they would only attack when touched/provoked, just like jellyfish in real life. I do think that people would very much so enjoy them being in game, considering their recent popularity that I mentioned in the beginning.
