Is there a cocktail named Jellyfish?

There doesn't appear to be a cocktail with the name "Jellyfish" that's widely recognized or documented.

However, there are some possibilities:

* Uncommon or Regional Cocktail: It's possible that a cocktail with that name exists but is only popular in a specific region or bar.

* Misremembered Name: You might be remembering the name slightly differently. Check if there are similar-sounding cocktails like "Jelly Bean" or "Sea Serpent".

* Creative Cocktail: Someone may have invented a cocktail with that name. If you have a specific bar or establishment in mind, it's worth asking them about their menu.

If you have more details, like where you heard the name or what ingredients you remember, it might be easier to pinpoint the cocktail you're thinking of.
