Hector Springs Loose — Elizabeth Shreeve

Hector Fuller is a wumblebug. A more likeable bug you'll never find. But you'll also never find a wumblebug anywhere other than the pages of a book -- this book, to be exact.
One morning Hector Fuller is playing the piano in his wumblebug hole, as content as a bug can be when his home is taken over by a hopping flea circus! Fleas are everywhere, hanging from the ceiling and bouncing off the walls. To make matters worse, Hector's allergic to fleas -- all six of his legs are itching like crazy! There's only one thing for poor Hector to do: He'll have to find a new home.
On his search, Hector meets new creatures and sees amazing sights, but will he ever find a home as perfect as his snug little hole?
