Jason Grilli and the Pirates' 'Shark Tank' bullpen take their mascots mobile

Jason Grilli and the Pirates bullpen have nicknamed themselves the "Shark Tank," and earlier this year, the group invited actual live sharks into their clubhouse.

And now, two fans have created a travel tank for these sea-faring beasts. That's right, Marty and Melissa Sigmund presented their team with a marine transport bag on Sunday and the Bucs will be able to bring their new pets to every away game.

How's everyone feelin' about that?
