JB Pumpernikel The Gardening Mystery

When the prize-winning garden is destroyed, JB recruits the help of his friends Sammy and Benny, who quickly find that many other gardens in the neighborhood have also been destroyed. But with no leads, JB and his friends find themselves at a dead end, especially when JB and Sammy end up playing babysitter to the annoying next-door neighbor, Casey. JB soon discovers that Casey is a child genius who has been doing some evil scientist modifications to the once innocent garden decor that is set out to destroy any garden, and any person, who stands in their way.
