Larry is a comical duck who appears to be laid-back and carefree. He gets along very well with his fellow farm animals and hardly has any worries or obligations. He also seems to enjoy the rare experiences that take place, especially the town fair.
Larry is first seen during the "Little Patch of Heaven" music number helping Pearl around the farm. He collects a bushel of corn for Ollie and the piggies to eat. Larry is later present when Maggie first arrives on the farm and stares at her with awe and wonder, as do the other farm animals, before she is welcomed by Mrs. Calloway.
Later, when Pearl's livestock face losing their farm due to a bank notice that she hasn't been able to pay yet, Larry is the first one to encourage Maggie when she has a lucrative idea. Sometime later, Maggie, Mrs. Calloway and Grace go on a quest to capture outlaw Alameda Slim and use the reward money to save Little Patch of Heaven.
After some time passes, Larry and the other farm animals start to worry about the cows. When Jeb makes a negative statement about the current situation, Larry suspiciously agrees with the old goat. When the other farm animals panic, thinking the cows abandoned them and will never return, Ollie manages to calm everyone down by getting their attention. He then tries to lighten things up by telling Larry and the farm animals that there's nothing those cows can't do.
In the film's climax, Larry helps the three cows (who have returned from their journey) battle a disguised Alameda Slim after he attempts to kill the bovines. Larry and the farm animals succeed in defeating Slim, who is then arrested by Sheriff Sam Brown. After Pearl uses the reward money to pay the bank's debt for Little Patch of Heaven, a photographer takes a picture of Pearl and her livestock, with Larry and the other farm animals smiling save Jeb.
Larry is last seen dancing with all the other farm animals as they celebrate Pearl's farm being saved and re-opened.
Out of all the farm animals, Larry has the fewest speaking lines.
