Atheneum Books for Young Readers, 1996

Description:

Steve hadn't liked it when his mom had started changing everything at home. She had gotten rid of his table and chair, and hadn't even asked him if he wanted his bathroom stool. But the new spaceship wallpaper in Steve's room was... well, fantastic. When Steve went to bed that night, he found out just how fantastic it was.

Another riotous ride through the heavens, piloted by veteran space captain Daniel Pinkwater, and his trusty co-pilot, Jill.
