Odd things are being stolen all over town - a bicycle, swimming trunks, the school's tractor mower. Nine-year-old Callie Major has other things to worry about: number one being her dreaded new hearing aids - or, as she prefers to call them, 'the Slugs'. But when she meets Bo, an abandoned Mynah bird, she discovers something amazing. Without her hearing aids, all the sounds Bo makes are merely chirping; when she's wearing them, though, she can hear him talk to her! Can she use her magical Slugs to help catch the thief and save the day?
