2. Encounter the Giant Mubcrab
There are plenty of mubcrabs to be found throughout Skyrim, however one in particular is rather special. To the west of Whiterun and just south of Gjukar's Monument is a small pool, containing a handful of regular mudcrabs to kill and the body of one giant beast!
Thankfully this Giant Enemy (mud)Crab is already deceased, as those pincers look big enough to cause massive damage with a single squeeze. However, if you undertake the side quest 'Kyne's Sacred Trials' you are sent back to this area to kill the spirit of this monster crustacean, finishing it off once and for all.
