• Ymir had three direct offspring: a boy and girl who grew from beneath his arms and a six-headed son who sprang from the coupling of his feet.

• In the stronghold of the giant Útgarda-Loki, Thor drank three mighty draughts from a horn during a drinking contest but gave up when he was unable to empty the horn of its contents; this was also one of three tasks he did -and failed- during his stay, the other two being to lift a cat and to defeat an old woman; it is later revealed that the horn was connected to the sea, the cat was the World Serpent and the old woman, the Old Age itself. Previous to this, Thor and his companions had met the giant, who was under the assumed name Skrýmir, in the forest outside the castle. When Skrymir had gone to sleep during their journey together, Thor became annoyed by his loud snoring and struck at him three times with his hammer, but in each case the blow was misdirected through magic and illusion.
