R to L (Japanese Style) Nine-year-old Noboru does the responsible thing and recycles a plastic bottle. But little does he know that the bottle is about to come back to life as PET, a robot with a mission: to pay Noboru back for recycling him! The only problem is that PET’s sense of "helping" isn't quite in touch with reality. Combining the visual appeal of manga with the episodic comedy of web comics, Leave it to PET!’s adorable characters deliver wacky humor in bite-sized installments! Who is the man behind the machines? The epic struggle to become Most Helpful Robot™ continues in volume 4 of Leave It to PET! Meet the genius who started the recycling robot craze, Dr. Wattawaste! Witness the birth of a new recycling robot! And see what happens in a soccer throw-down between the Gadget Design department and Team Robot! When Noboru recycled a plastic bottle, he never thought he'd get a devoted PET in return!
