The gods were confident they could get everything on earth to weep for Balder, the sky wept and the flowers eyes were filled with dewy tears. They never would have suspected what was to come
It was all going well until they encountered a ugly old giantress named Thokt who refused to cry for Balder, "Balder is nothing to me, i care not whether he lives or dies..."
After getting word of the terrible news Odin cried that it was Loki himself! who had tricked them once again and disguised himself as the giantess
Thor with anger yelled out that the time for mourning was over and the time for revenge has come to punish Loki for his wrong-doings
Loki knew that sooner or later he would be found out and so he ran to the mountains and built himself a castle of rocks, where he stayed alone and played his favorite game which was to turn into a salmon and splash around pool below the fall
There Loki lived until one day while he was tinkering with a new invention, the fishing net. Loki saw the Aesir, not wanting them to find his invention he threw it in the fireplace and turned himself into a salmon swimming away
