The 26 animatronics at Duck-Billed O'Malley's Pizzeria and Bowling Alley could be divided into five groups of five (with a remainder of one). Each of these groups corresponded to one of the five areas in and around the alley that used animatronics.

The main stage was located at just the right spot in the bowling alley so that everyone could always have a good view of the stage from any spot of the alley that wasn't the backrooms, the lake, or the parking lot. The main stage featured musical performances from Duck-Billed O'Malley and his band every hour on the hour. These performances would typically last 15 minutes each. After which, the band would come down from the stage to mingle with the alley's patrons for half an hour, before retiring backstage for maintenance before the next show.

On top of being the face of the entire establishment, Duck-Billed O'Malley served as the lead singer of his band when performing on the main stage. After closing time, O'Malley and four other animatronics would occasionally join Scott Williams on a nighttime outing if rumors of monster activity near the bowling alley reached Scott's ears. During these outings, they would determine the truth of these rumors and act to end any threat posed by these monsters if the rumors were true. They would do so peacefully if possible, but would resort to violence if the monster in question was unreasonable enough to make it necessary. O'Malley has the voice, speech patterns, and mannerisms of Henry McDevitt, a brutal Irish gangster who vanished without a trace in the mid 1980s.

She had the voice, speech patterns, and mannerisms of Arwen Fleet, a Welsh anarchist who vanished without a trace in the mid 1980s.

The backrooms were the name collectively given to any room in the bowling alley that only staff were allowed into. When the alley first opened, the bowling lane technicians had an animatronic assistant to help them out and keep their spirits up. In the early 1990s, Scott began introducing animatronic assistants to other sectors of the backrooms to reward the good work of the employees assigned to those sectors. An additional four animatronics had joined the first one by the time 2020 rolled around.

Patterdale Abernathy was a Patterdale terrier animatronic who served as a technician in the backrooms behind the bowling lanes.

The front desk was something of an odd one out among the areas of the bowling alley that used animatronics. Because while all the other areas had several, the front desk only had one.

In the early 1990s, the bowling alley had become popular enough to draw in visitors from not just across the city, but from beyond it too. As a result, the demand for parking space began to grow beyond the ability of the human parking attendants to manage effectively. And so Scott did what he always did in times like these: He built more animatronics to help ease the burden and raise morale. It started with two animatronics in the early 1990s, then two more were added in the mid 1990s, and then one last animatronic was rolled out on the tail end of the decade.

Ivory Tassiter was an ivory gull animatronic who was rolled out during the the early 1990s to serve as a parking warden.

A private lake next to the alley had been a part of the property long before it came into Scott's possession. He'd had plans of creating some kind of aquatic animatronic show there from the very beginning, but it wasn't until the early 2000s that he devised the means to create water resistant animatronics. The lake show featured five animatronics and was an hourly event, each show taking place at the thirty minute mark of each hour and lasting about 15 minutes. There was music during the first five minutes, an encounter with the lake show's antagonist during the middle five minutes, and a storytelling during the last five minutes. After that, boat rides and interaction with the animatronics would be available to customers for half an hour, after which point the animatronics would retreat for maintenance before the next show.

Great White Rowe was a great white shark animatronic who served as the lake show's antagonist. Unlike most of the other animatronics, Rowe had an anatomically correct appearance rather than a humanoid figure, so he actually looked like a real life shark (albeit with some cartoonish alterations here and there). After closing time, he served as an escort to Humpback Simard during nautical expeditions. He had the voice, speech patterns, and mannerisms of Kenny Parker, a corrupt Australian police chief who vanished without a trace in the late 1990s.
