Thorvar's bucket was an item used in the 2010 Christmas event, given to the player by Thorvar Crittersmash. Thorvar says "When the time comes, you'll know what to do." If you clicked on 'find a use for bucket' you would simply be reminded of his advice.
The bucket was used in the final room of the event dungeon to catch the "horrible creature" Thorvar refers to, Salty Claws. Once caught, the bucket containing Salty Claws would be taken to Thorvar.
