A Sea slug is an item that players can pick up using the Telekinetic Grab spell on a sea slug that Kent knocks off the player during the Sea Slug quest.
Without Telekinetic Grab, it will merely damage the player for 3 hitpoints, causing them to exclaim "Ouch!" If dropped, players can only pick it up again using another Telekinetic Grab spell.
- A player can be damaged by them even on free to play worlds.
- When you ask the Wise Old Man to check your bank for junk while a sea slug is in it, he will comment "A Sea Slug? Yuk! Get rid of it!"
