Wait, wait, wait... make a dungeon, where something is sealed - something like the... Tarrasque!
It's contained in a massive block of the hardest non-adamantium alloys (hardness 15-19), and the tarrasque is constrained by manacles of magical force. If they do the dungeon correctly (without spoons), then they can get in, fetch the "insert plot item" and then go out.
If they're spooning, they lessen the structural integrity of the dungeon... and...
Yeah - let them survive and come on terms with their guilt and error.
It's not even particularily nasty, because dungeons are more then treasure chambers - they've got a in-game relevance - like locking up some things for a long, long, long time.
