Books in the Scooper and Dumper series

"Crisp fall days are here, and Scooper and Dumper are in high gear, getting ready for the pumpkin parade. From hanging lights to moving hay bales, they're a terrific team. The night of the parade, they have everything together but the pumpkins. So they head over to Maybelle's farm. But rounding everything up isn't so easy. And what's that spooky noise in the cornfield? Could it be a ghost?"--
