Emma and Corny first appear in "Pups Save a Wedding" where they get married, alongside their owners in a double wedding.
In "Ultimate Rescue: Pups Save a Runaway Stargazer", Emma gives birth to three piglets. When Ryder warns Al and Yumi that the Adventure Bay observatory is headed towards their barn, but Al and Yumi reveal the newborn piglets can't be moved, forcing Rubble and his Ultimate Construction Rescue Crew to build a ramp using the roof of Farmer Al's derelict shed, to prevent the Observatory from harming Emma and her piglets.
Emma and Corny love each other very much; they are often seen hugging and rubbing against each other in episodes.
Emma and Corny are almost equal in size as pigs. Emma has light pink fur, while Corny has cream fur with brown patches. Both pigs have brown eyes and black hooves.
