A 50-foot rubber duck was wading in the waters of the Thames River in London Tuesday, forcing the city’s famed Tower Bridge to part so it could continue on its journey as part of a Facebook game company’s promotion.

You can view the video of the 50-foot duck above. The inflatable rubber duckie weighed half a pound and took 800 man hours to create.

“The duck’s behaved impeccably. It looked great. It may look unusual, but to us it’s a regular day in the office,” said Nick Runeckles.

A woman identified as Barbara Windsor and described as the patron of the FUNdation said the 50-foot duck set sail “to spread some silly fun and laughter throughout the city and to celebrate the launch of the Jackpotjoy FUNdation.”

The company was vague on exactly what the FUNdation is, but the Jackpotjoy Facebook page urges the game’s users to come up with their own ideas for fun.

“Yesterday we sent a giant duck down the Thames to launch the Jackpotjoy FUNdation. What would you like us to FUNd next? Share/Like and Comment to be in with a chance to win 500 Joy Points,” the Facebook page read.

Jackpotjoy is a Facebook game geared toward residents of the United Kingdom and features casino, bingo and jackpot-style games.

Jackpotjoy’s parent company is the London-based GamesysGroup.

The video of the 50-foot duck was also shown on Jackpotjoy’s Facebook page. The video was shared 17 times and liked by 38 Facebook users.

Facebook user Tracey Blowman wrote, “brilliant jpj,that duck made me laugh dived under water haha.”

The 50-foot duck floated along the Thames and passed by a number of London landmarks, according to Windsor.
