To remove my tongue helped, but made it very inconvenient to push meat into my maw. Adding the state of the carcass to the equation, consuming it took me thrice as long as usual, and by the end, I was covered in the creature's disgusting blood all over.
But even the perspective of feeding (on) fishes in the near future didn't diminish my elation when I saw the notification that I got 4 million EXP from the monster and new abilities. Four million for a creature this size meant that its abilities were something the System thought was worth plenty of EXP.
