The hunt is on for a big blue wacky waving inflatable arm flailing tube man who went missing during Oktoberfest celebrations in Perth’s Swan Valley at the weekend.

‘Mr Wiggly’ was last seen on Saturday for the annual Elmar’s in the Valley event.

“We understand after a few drinks these things seem like a good idea & some fun and games at the time. BUT we would love our inflatable Mr Wiggly Man returned,” the German restaurant posted on social media.

The owners said they would even swap it for a 6 pack of beer.
