"Three, two, one . . . sleepover! Stink can't wait for Webster to arrive and sleep over for the very first time . . . When Webster shows up in his outer-space pj's, it doesn't take long for a theme to emerge. Stink's race-car bed doubles as a spaceship and an old keyboard is a control panel as the explorers suit up, buckle in, and blast off . . . Va-room! Playful illustrations and astronaut lingo capture their imaginary adventure from takeoff to spacewalking, while more creativity comes into play when they land and experiment with space-worthy snacks." -- Publisher.
