In the cool, crisp state of Massachusetts, aptly nicknamed "The Codfish State," a bunch of exuberant kids have discovered an exciting secret. They've become masters of the swish and the swoosh, the roll and the pin - they've become Jiu-jitsu enthusiasts! Now, allow me to introduce you to the most famous of these Massachusetts Jiu-jitsu youngsters - a boy named Boston Bumblebee Barry. Don't let the name fool you, Barry isn't a buzzing insect, but he's buzzing with energy alright! He's a 12-year-old with a smile that could outshine a lighthouse and a sense of humor that could tickle a crab into laughter. When he's not busy with schoolwork or trying to invent the world's first marshmallow pizza (because, according to him, it could be a revolutionary form of dessert), you can find him at the local Jiu-Jitsu dojo. Here, Boston Bumblebee Barry, with his golden gi and black belt, rolls and tumbles on the mat like a playful seal, while his fellow Jiu-jitsu buddies cheer him on. These Massachusetts kids are not your ordinary lot. They’ve become experts at twisting and turning, grappling, and pinning, all while maintaining the concentration of a wise old owl and the agility of a frisky squirrel. They have turned the ancient martial art of Jiu-jitsu into a game as fun as a wild clam-bake party on a sunny beach. And just like a clam, they've learnt to toughen up on the outside, while keeping their hearts soft and kind. They may be Massachusetts 'grapplers' on the mat, but off it, they're just regular kids with big dreams, hearty laughs, and an unending love for marshmallow pizzas, thanks to Boston Bumblebee Barry, of course!
