This was years ago. Like 2014? Never found it ever again...

It was some kid's show in a Scandinavian country. The whole video had some weird repetitive chanting. There was an army and I guess they were friends with a giant. And he carried them across the ocean in their ship or something and then they massacred the enemy army extremely graphically. This giant (might have been a cyclops even?) Was swinging the ships at the enemy and decapitating like 10 at a time rofl.

I've looked for it for years.

i think the animation you are looking for is suur-töll, an estonian mythologic animation
