Yuck! Stuck in the Muck by Corinne Demas, illustrated by Laura Rader.
Dog chases Duck into the swamp, setting off a very muddy chain of events. Chuck tries to pull Dog out of the muck and also gets stuck. One by one, each character gets stuck while trying to help another. At last, a helicopter rescues them, and Duck flies back to build a nest on the still-stuck truck!
