Belly Flop! is the third book in the Mal and Chad series.
A time machine? Mal can build one with his eyes closed and one arm tied behind his back. His secret crush's birthday party? Gulp.
A shrinking machine. Invisibility spray. If Mal can think it, he can build it. But there's one thing he can't seem to do: Get Megan to notice him. He gets his chance when he's invited to her birthday party. But destroying her cake and presents wasn't quite what Mal had in mind.
Good thing the school's talent show is coming up! Megan will really be impressed when she sees Mal levitate for real and . . . uh-oh--cause a major blizzard?? Yikes! Who will go rescue Mal's talking dog best friend, Chad?
