Sea meat

The Sea meat is a food item found during the Fremennik saga, Thok It To 'Em. It has the same appearance as a Raw cave moray, but can be eaten to recover 250 LP of damage. Thok eats it raw as he "likes the taste better". The player is given a number of these before the walking icecube battle, and may receive a few off some uglies.

More is found in Thok Your Block Off, dropped by various monsters and in Thok's inventory at the start of the saga. It still heals 250 life points, but now looks like Bouldabass.
