Paul, the octopus who became a pop culture sensation by correctly predicting the outcome of eight World Cup matches, is becoming a darling at the ongoing Shanghai World Expo.

The International Development Information Network Association Section, one of the pavillions of Expo 2010, announced on Monday that it would offer stamps featuring the octopus "Paul" to visitors as of the final whistle of this year's World Cup.

The initiative has soon attracted a great amount of Expo fans to seek the stamp, which printed a cartoon octopus with the words "Octopus predicts the football match winner" on it.

"We plan to seal the stamp by two weeks from now on," said Shen Dan, staff of the pavillion told Xinhua.

Paul won worldwide attention as he called all of Germany's games correctly, including its semifinal defeat by Spain. He crowned his career by forecasting correctly that Spain would beat Holland in Sunday's final.

Upon Tuesday, more than 26 million people have visited the World Expo Park in Shanghai since its official opening on May 1.
