IMDB

A wrestler wins the world championship, but isn't even given time to celebrate before a giant squid attacks him. Soon everybody wants to see the squid and the champ in a match, but the squid won't work a fixed match. They agree to do it shoot-style. In the meantime, the squid steals the champs girlfriend.
The first 45 minutes are fast-paced and outrageous. During the last half the novelty wears a little thin, but the story keeps you immersed until the end. Lots of absurdity in this one. If you want to see a squid wrestle and octopus then pick this one up.

8/10
