Team Kramer's youngest member Gavin just had a stinkin' awesome birthday celebration

Team Kramer's youngest, Gavin, just turned five and his family threw him a  stinkin' awesome "Grossery Gang" birthday party.

Mom Cheska shared the scenes of his party on her Instagram account, and allow us to tell you: Everything looked gross — and cute! There was Gavin's toilet seat throne, animated rotten junk food table toppers, cupcakes, and to his birthday cake.

Their party favors made it even more exciting: crayons and other art materials, yucky pillows, plus a face paint station and a cookie-making station for the kids.

Take a look at the photos of Gavin's 5th birthday celebration in this gallery.
