From planet Smoo, the King, grateful for his son's rescue last year, sends Akiko, Spuckler Boach, Gax, Poog, and Mr Beeba on a paid vacation to planet Quilk, home of the Intergalactic Zoo. Creatures wander in every shape, color, and size, hard to distinguish from visitors. How will Akiko escape when the zookeeper adds her to his personal collection?

Akiko and her crew–Spuckler Boach, Mr. Beeba, Poog, and Gax–are competing in an intergalactic race from one side of the universe to the other.

All Akiko wants to do is make it back to Earth in one piece! But when Spuckler discovers that his old rival Bluggamin Streed is also in the race, winning becomes the most important thing. And Akiko quickly finds herself caught up in the competition. Who will go home with the celebrated Centauri Cup? From the Hardcover edition.

“Poog’s in trouble.” Just three simple words, but they’re enough to launch fifth-grade Akiko and the rest of her crew—Spuckler Boach, Mr. Beeba, and Gax—on their next mission. And it just might be their most important mission To save the planet Toog, home of their good friend Poog. Someone’s out to destroy Toog, and only Akiko and the gang can stop them. But first they have to escape from a Toogolian jail cell, zoom through a barrage of exploding drobe mines, and enlist the help of Spuckler’s old friend Fluggly Ragstubble—who’s anything but helpful. The clock is ticking and every second counts. Will they win the race against time and save Poog’s home planet?

When Akiko’s Smoovian friends, Poog, Mr. Beeba, Gax, and Spuckler Boach, swing by to pick her up in an astroshuttle, she’s feeling bored with her “normal” life and more than ready to go—anywhere. What she doesn’t know is that King Froptoppit has enrolled them all in the Intergalactic Space Patrollers Training Camp on Zarga Baffa. Every planet in the universe relies on patrollers for protection, but no one from Smoo has ever graduated. Akiko and her crew are the planet’s last hope. After a freak accident at nearby Virpling Canyon, Akiko’s crew faces the ultimate final exam. Will Akiko go home, leaving the rescuing to others? Or will she stay and risk everything? From the Hardcover edition.

Akiko's always prepared for something out of this world, but when she goes on a pleasure trip to Gollarondo with Poog, Mr. Beeba, Spuckler Boach, and Gax she can barely believe her eyes—Gollarondo is a city that was built completely upside down! Forget sight-seeing. All Akiko wants to do is keep both feet on the ground. Which is not so easy. Almost as soon as the gang arrives Spuckler's robot Gax accidentally flies off one of Gollarondo's balconies and into the Moonguzzit Sea below. Good He survived the fall. Bad Anything and everything that falls from Gollarondo is automatically the property of Nugg von Hoffelhiff—the ruler of the seas beneath the city. By the time Akiko and her crew are able to gain an audience with Nugg, he has sold Gax to others. What's worse, he actually broke Gax down into spare parts to maximize his profits! It's up to Akiko and the gang to retrieve the pieces of Gax before they are spread far and wide across the Moonguzzit Sea. But the people who bought the parts run the gamut from off the wall to downright villainous, so saving Gax's neck (and body and wheels) may turn out to be Akiko's most dangerous mission yet.

AKIKO NEVER KNOWS when her next adventure will zoom her away to another galaxy. And when she’s visited by the Akiko replacement robot in the middle of the first annual Middleton Mega MangaFest, she’s more than eager to visit her friends on planet Smoo. But when Akiko lands on Smoo, it’s different. And so are her friends. King Froptoppit’s castle is smaller, no one has any idea who she is, and Mr. Beeba has—no way!—a full head of hair. Akiko got to planet Smoo all right—but it’s planet Smoo 25 years ago. And now that Akiko is part of Smoovian history, she might just change it. For the worse!
