Tangle Kelp

This datapack transforms ordinary kelp into a dangerous trap for players. When you touch the kelp, it begins pulling you downward, applying the slowness effect and periodically dealing damage. This turns harmless underwater plants into a serious threat for careless swimmers.

Want to change which creatures are affected by the kelp? You can configure this through the tanglekelp/tags/entity_types/tangles.json file, where you specify all entity types that will react to the new dangerous kelp.
