Jelly Sculk
A jellyfish sculk creature.
Origin ID: proviorigins:jelly
The Jelly Sculk sacrifices its combat prowess for powerful exploration abilities. They are extremely fragile with only 5 hearts, but are immune to fall damage, can gain speed on sculk, and can double jump.
Its main power is its ability to see the world through vibrations; the Jelly Sculk can detect vibrations made by living entities, including vibrations passed through a sculk sensor. However, the Jelly Sculk can only see entities after detecting their vibrations, leaving them completely vulnerable to sneaking players and entities on wool/carpet.
With their ability to emit no vibrations themselves, the Jelly Sculk can safely and quickly loot Ancient Cities, potentially gaining a strong early advantage.
