Suttungr

The dwarves begged for Suttungr to spare their life and offered him the magical mead of poetry.

Baugi drilled into the mountain and Odin changed into a snake and slithered inside.

Inside, Gunnlöð was on guard but he persuaded her to give him three sips in exchange for three nights of sex.

[2] Odin proceeded to drink all the mead in the three containers, changed into an eagle and escaped.

Suttungr chased him in the shape of an eagle, but Odin was able to escape him and returned to Asgard.
