Party at T-Mobile Park: Celebrating Mariner Moose’s Birthday with Party Baby Seattle!

Updated: Jun 1, 2026

Hey there, Party Baby fans! We’ve got an exciting update to share with you today. Last weekend, Party Baby teamed up with the Mariners once again for an unforgettable event  – none other than the Mariner Moose’s birthday bash! This was truly a major league celebration. We were thrilled to bring the fun and excitement for the Moose’s big day.


We Went BIG for the Moose’s Party

The private event took place before the Mariners game against the Cubs – and we won! Setting the mood for the day was a priority for our team. As a main attraction at the party, our goal was to ensure everyone had a blast. Judging by the kiddos smiles and laughter, we think we hit it out of the park. 

We went with the Super Luxe Ball Pit and filled it with over 4,000 team-colored balls. This transformed the venue into a whimsical playground with an exciting atmosphere. It was a huge hit. Kids lined up to slide down into the sea of balls or jumped into the ball pit, laughing and having the time of their lives!


Star-Studded Mascot Fun

Joining in Moose’s birthday celebration were local favorites, including Weebly from the Aquasox, Fin Crispy from the Fishsticks, Harry the Husky from the University of Washington, and Boom from the Seahawks. They brought their infectious energy, entertained the crowd, signed autographs, and offered once-in-a-lifetime photo opportunities with the kids.

The mascots clearly know a good time when they see one! They couldn’t resist the fun. They all took turns in our ball pit and joined the kids, creating unforgettable moments for everyone there.


Proud Partnerships and Unforgettable Memories

We are incredibly proud of our partnerships with the Mariners and Seahawks. We truly appreciate the trust they place in us to bring the fun to their events. 

Whether we’re setting the stage for a professional sporting event or crafting the perfect space for a child’s first birthday party, our goal is always the same. We aim to create unforgettable memories that last a lifetime.  

Whether it’s a private event or a quaint backyard party, Party Baby Seattle’s vibrant decorations, interactive activities, and hassle-free service can transform any occasion. We make it an experience unlike any other!

Thank you, Mariners, for having us!
