Watch: Mariners' mascot ruins mannequin challenge attempt

You had one job, Moose.

With the newest viral social media trend featuring soccer stars, football celebrations, and even basketball crowds, a handful of MLB mascots took it upon themselves to try to create their own mannequin challenge. They were nearly successful, too, until the Seattle Mariners' mascot, "Mariner Moose," ruined the effort by forgetting to put his phone on vibrate.

While they still had a chance to dub the music over and save their attempt, Moose completely derailed the challenge when he reached over and picked up the call.

He probably won't be invited back the next time they try.
