Toby and Jacob Wiggler were fun, adventurers, brothers and best friends, but more important....they are inventors! As Toby and Jacob spent their days, having fun, they were always found adventure and usually crazy problems. With each problem Toby and Jacob think up a solution...an invention. The inventions work one way or another, but wacky things happen and the two end up in trouble. This summer the boys go fishing and are faced with another wacky problem, a giant worm. They invent and get into trouble as usual. What will they invent this time? And what wackiness will they find this time?!
