Christmas pudding was available during the 2011 and 2016 Christmas events. During the event, players can find a Christmas pudding in the toy box next to Timmy's cage. In order to receive two lesser demon claws for the banquet, players throw the pudding at Timmy to anger him into dropping his claws.
When eaten, the player character stops and says "Delicious!". This is merely cosmetic and has no effect. The 2011 Christmas pudding was subsequently removed from the game after both events.
