A host of MLB mascots descended on Citizens Bank Park, Philadelphia yesterday, apparently there to celebrate the birthday of one of their own, the Phillie Phanatic.
With so many inflatable characters in one place chaos was never likely to be far away, as one unlucky MLB umpire found out to his cost during the Phillies - Cincinnati Reds.
As the video shows, Clammy Sosa, the mascot of the visiting Reds, took the opportunity to cause havoc as he spotted the third umpire in his sights.
Running at full speed towards him (which is no mean feat for a giant inflatable clam), the mascot bore down on the hapless official before eating the poor guy whole!
As you can see from the rest of the footage, it wasn't your average day in Philadelphia.
There was some actual baseball played Sunday too amidst the carnivorous activity, with the Phillies winning out 8-3 against the Reds.
