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?

Fifth-grader Akiko renews her acquaintance with her friends from the planet Smoo when they whisk her away to the Zarga Baffa Training Camp, where she must deal with mud, misery, and a training master who is out to get her.

When fourth grader Akiko finds a spacecraft hovering outside her window one night, she begins the adventure of a lifetime. She is whisked off to the planet Smoo to lead a team searching for the King of Smoo’s kidnapped son. Akiko the head of a rescue mission? She’s afraid to be on the school’s safety patrol! So begins the adventures of Akiko, wherein she meets her team — Spuckler Boach, Gax, Poog, and Mr. Beeba — and sets off on a journey across Smoo to find a prince and become a leader.

Akiko and her crew — Spuckler Boach, Mr. Beeba, Poog, and Gax — have faced dangers unimaginable to the average fourth-grade earthling. Now their mission is finally coming to an end. At last they’ve reached the castle of Alia Rellapor — but that doesn’t mean that things have gotten any easier. The castle is heavily guarded by robots and getting inside won’t be easy. If they do get in, they have to locate Prince Froptoppit, free him from captivity, and escape from the castle without alerting the guards or their leader, the half man — half machine Throck. Can a girl who’s too scared to be school safety leader pull it off? If anyone can, Akiko can!

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. Along the way they have to make it through the narrow passages of the Labyrinth of Lulla-ma-Waygo, the notorious Almost Black Hole of Luzbert-7, and the deadly Jaws of McVluddapuck. 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?

Sixth-grader Akiko and her friends from the planet Smoo travel to the upside-down city of Gollarondo, where an accident befalls Gax the robot and a search begins for all his missing pieces.

Akiko's back! No longer simply a shy fourth-grade girl, she's become an intergalactic leader, taking her band of would-be heroes on a quest to find a kidnapped prince! Armed with a map showing the way to Alia Rellapor's castle, Akiko, Mr. Beeba, Spuckler, Gax, and Poog are nearing the end of their mission. But first they have to scale the Great Wall of Trudd. Like the Great Wall of China only bigger, the Great Wall of Trudd stretches across the landscape -- there's no way around it, under it, or through it. So Akiko and the gang will just have to find a way to go over it! But the Great Wall is just one of the many strange obstacles in their path that Akiko must overcome if she's finally to rescue Prince Froptoppit.
