Being a type of pain block, a Sea Urchin knocks the player back and stings the player until the player stops all motion. A player will die after making contact with a pain block five times in quick succession (recovering from damage takes roughly 5 seconds). The Fireproof mod will not allow the player to take more hits, unlike with lava pain blocks.
