The truffle crab in "Stardew Valley" is a very important special animal in the game. If you want to find truffle crabs, you can first build a pig farm. Truffle crabs can only be found on a farm where you already raise pigs. It only appears when a pig digs up a truffle, and there is a 0.2% chance that a truffle crab will appear.
Where does the truffle crab appear in Stardew Valley
Truffle crabs will only appear on farms where you already have pigs. When a pig digs up a truffle, there is a 0.2% chance that a truffle crab will appear (instead of a regular truffle).
At first glance, the truffle crab looks just like a truffle, but as you get closer, its little green legs appear and start moving around. These crabs are almost identical to the regular crabs you find in the mines.
Since pigs can only collect truffles outside, you won't find truffle crabs in the winter. Pigs stay in pens during this season.
