When Sparky's magic bone blasts him to Tokyo, Japan, he discovers a whole new world--one with karaoke, "squishy fishy" and sumo wrestlers! His new friend, an Akita named Nanami, guides him around the city, until Sparky loses her in a crowd. But it turns out Nanami isn't just any Akita.

She's the queen of the Ninja Dogs--a fierce group who are convinced that Sparky has kidnapped her! To make matters worse, the Ninja Dogs have Sparky's magic bone, and won't return it until he leads them to Nanami. It's up to Sparky to reunite the Ninja Dog family so he can return home to his own!

Sent to the backyard for breaking a tick-tock-ticking toy, Sparky (an adorable but clumsy sheepdog puppy) immediately begins his favorite activity: diggety-dig-digging. Little does he know, he's about to dig up the most amazing toy ever--a magic bone!

With one bite into that sparkling bone, Sparky is magically transported to London, where he makes new friends, sees the sights, and gets into a bit of trouble. Join Sparky on his adventure to see how he escapes and makes it back home!
