Chapter one
Mario and Luigi, the twin plumbers, tackle everyday problems across their new home of the Mushroom Kingdom — supporting Princess Peach and keeping a very small, very grumpy Bowser in line. But when Peach’s birthday party sparks a galactic adventure, the brothers blast into space to stop Bowser Jr.’s wicked ambitions and save Rosalina.
New digs, familiar chaos. The brothers unclog the Mushroom Kingdom by day, babysit a miniaturized Bowser by night — and meet a certain green, hungry stowaway named Yoshi.
Peach’s birthday party lights up the kingdom — until a wish rockets skyward and the whole celebration goes cosmic. Suddenly “over the moon” isn’t a figure of speech.
Bowser Jr. is painting trouble across the stars, and Rosalina — guardian of the Lumas — is in his sights. Gravity optional. Courage required.

Seven little worlds, one big adventure. Give each planetoid a prod — they like it.
