Octopus Paul has become one of the stars of the tournament and put the TV pundits to shame, thanks to an amazing run of correct World Cup predictions. Here's 10 things you didn't know about the tentacled tipster.
1. He's originally from Weymouth
Although he now resides at the Aquarium Sea Life Centre in Oberhausen, Germany, Paul was actually born in Weymouth and moved from the town's Sea Life Park in 2006.
Fiona Smith, from Weymouth Sea Life Park, told the Dorset Echo: “He never made any predictions while he was living here but maybe he was waiting for a big event like the World Cup until he revealed his abilities.”
2. He's a wanted man
Argentine chef Nicolas Bedorrou was so angry after Paul correctly predicted his team would lose its quarter-final clash with Germany that he suggested a way to cook the octopus.
He posted on Facebook: "We will chase him and put him on some paper. We will then beat him (but correctly!) in order to keep the meat tender and then put it in boiling water."
3. He's big news
Paul's predictions have gained so much popularity that German news channel NTV has started to broadcast his predictions live, with two reporters situated next to his tank so they can bring their viewers all the latest goings on.
4. He's the biggest celebrity in Oberhausen
Having wowed the world's media with his predictions, Paul has put the mundane Germany city of Oberhausen on the map. Oberhausen, which is twinned with Middlesbrough, also boasts such sights as Germany's biggest shopping centre and Europe's largest disc-type gasometer. Worth a visit then ...
5. He's got a good track record
Paul began to predict Germany's results during the Euro 2008 tournament, correctly choosing the winner in four of Germany's six matches. He predicted Germany to win every match but was wrong when they lost to Croatia and in the final to Spain. So far at the World Cup 2010, Paul has correctly predicted the winner of each of Germany's five matches.
6. He could have made you a packet
Having correctly tipped the winner of Germany's five World Cup matches, backing Paul's tips could have netted you a few squid (sorry).
A £1 accumulator bet on all five results would have won you £131, which could comfortably buy you a few bags of mussels.
7. He's an intelligent creature
Octopuses are highly intelligent animals and have been proven to have a strong short and long-term memory.
Fiona Smith, head of animal care at Weymouth Sea Life Park said: “Common octopuses like Paul are very intelligent. We equate their intelligence with that of a dog and they love problem solving and figuring things out."
8. He's a Twitter and Facebook sensation
Paul has become an online phenomenon over recent weeks and is now one of the most talked about topics on the web. The phrases "Paul the Octopus" and "Pulpo", the Spanish word for octopus, are both currently in the top 10 global trends on Twitter.
9. He doesn't cheat
Paul predicts results by opening one of the two flag-covered plastic food containers in his tank. Tanja Munzig from the Sea Life Centre in Oberhausen has denied any suggestions that the containers are rigged.
She said: "There are no tricks, the food is the same and everything in the two containers is the same except for the flags."
10. He's not scared of death threats
According to his keeper, Oliver Walenciak, Paul is unfazed by a series of death threats sent by Argentinian supporters who blame the octopus for their World Cup exit.
He said: "There are always people who want to eat our octopus but he is not shy and we are here to protect him as well. He will survive."
