Seaslug

A Seaslug is an item that can be found on the Fishing Platform during and after the Sea Slug quest.

If a player attempts to pick it up, they will exclaim "ouch," and be hit for a small amount of damage, the amount of which is dependent on the player's current Hits level.

The only way for players to obtain this item is to cast Telekinetic grab (requiring level 33 Magic) on it. If dropped, Telekinetic grab will need to be cast again in order to pick it up.
