Swamp (Diggable)

It is possible to dig up Dead Snakes, Small Diamonds or rarely a Leech by using a Shovel or equivalent on this tile. After digging up an item, you have to wait a week to be able to dig any of these tiles again.
Existing locations are:

• West from orcs, here.
• South-west from orcs, here
• Two splots in a slime cave, here and here
• North-west of the slime cave, here
• Three inside the Rotworms cave here, here and on the lower floor here

Eeven though the first public hint for swamp digging was published in August 2008's Feature Article, it was only implemented in the game 4 months later with the Winter Update 2008.
Leech was added as a possible item to be digged up from this special kind of swamp with the Winter Update 2012.
