Factual errors

In the beginning, Dex and Sunshine sit down for a fancy dinner. The table is covered with grapes, a carton of milk, and ice cream with fudge topping. Dex eats raisins and drinks milk throughout the film. None of those foods are good for dogs; raisins and chocolate can be fatal to dogs. Raisins are also fatal to cats, and Sunshine is a cat-human hybrid.

Continuity

Near the beginning, Sunshine plays with a melon ball, which is animated on the top. When the perspective switches to just behind a child's head, with Sunshine in the background, the ball passes in front of the child's head when it should go behind it.

Revealing mistakes

In the opening scene, when the store's parking lot is shown, one street lamp overlaps a car that should be in front of it.

Continuity

During the final food fight, the food the good guys keep throwing at the villains appears in their hands out of nowhere between frames. When they throw the food, new food appears instantly.

Continuity

General X falls when Dex pulls the rug out from under him. Sunshine is tied to a chair on the same rug, yet she doesn't move. After Dex tugs on the rug, it's back to normal in the next shot, and General X seems to be falling back by himself.

Plot holes

Dex flies on a sealed soda bottle before the bottle cap is knocked off. A string was attached to the bottle in the original trailer, but it was removed from the finished version.

Continuity

Sunshine's cat ear constantly disappears and reappears.

Plot holes

The mechanics of the movie's world change depending on the scene. In the beginning, all the food icons become active after the store closes for the night, and they have to disappear when the store opens in the morning. During daytime, the Ikes seem to be aware of what's going on in the real world, but are unable to react to it. Later on, the Ikes walk around the store in broad daylight, among the humans. When they "break through" the store shelves, they appear back in their own world. Later still, Mr. Clipboard somehow shows up inside the market world, and Lady X reveals that she's had plastic surgery and seduced humans, despite being a brand mascot the size of a human hand.

Continuity

When the watermelon hits Dan, it produces a bright green splat, even though watermelon is red on the inside. When another melon is thrown during the final food fight, it's red when it breaks apart.

Revealing mistakes

When the hairless hamsters fall out of the sky, they are flattened before they reach the ground.

Anachronisms

Sunshine disappears because Brand X recalls Sunshine's raisin brand. Some companies produce food products that are sold under numerous brand names. For example, a 2016 ice cream recall included 3 brands that used the same supplier.

Revealing mistakes

The animation throughout the film is rushed and unfinished. Characters often lack facial expressions, their lip movements don't match their dialogue, and several solid objects go through one another.

Revealing mistakes

The audio quality throughout the movie is inconsistent. Some of the voice actors' lines were recorded with different equipment.
