a dragon, the ice, and a cow

One lick two licks Three licks four Will this take a day or more Here I am licking Licking on the salty floor I can almost see the man Sleeping in the core This has worked in the past This salty, ice-like stone I had helped the mightiest The king up on the throne Ymir had sent me off To do what I must do To help all the others Who's never seen the moon I licked for three days straight I did The foolishness I had Didn't stop when I saw scales By that time I was already dead What had I been licking It wriggled and it breathed Was it asking for assistance? No, it was trying to be freed Nidhogg had escaped My fault, but in what sense, how Well this my friend is simple I'm literally a cow
