Continuity mistake: When the chipmunks are cooking toaster waffles, they finally pop out of the toaster and fly all the way across the counter. Simon runs after one but doesn't catch it and it lands in front of him. In shots from the point of view of Dave, Simon is standing with the burnt waffle on the counter in front of him; and around him there are condiment shakers, food packages, utensils and a knife block. However during this scene there is a shot that has the camera behind the counter to show both Dave and Simon. However in these shots none of the aforementioned items surrounding Simon are there apart from the burnt toaster waffle. (00:21:55)
Continuity mistake: In the scene where the chipmunks are on the set of the Crunchy Nibbles advert, they are each standing in front of a bowl of the nibbles. But they are completely knackered, and Theodore falls forward into his bowl, causing nibbles to spill all over the table. However in the following shots the amount of nibbles around the bowl on the table is inconsistent. (01:03:20)
Continuity mistake: When Dave gets home from Jett Records he goes into his music study grabs all of his instruments and other equipment and throws it out into his front garden area, in a fit of anger. However a bit later in the film when he discovers the chipmunks (and their singing abilities) he goes back out to retrieve all the items; however now they are all in totally different places to where they were when he threw them out. (00:10:00 - 00:18:20)
Continuity mistake: When Dave awakens after being knocked unconscious by the jar in the kitchen, he stands up next to the sink and in the sink there are two coloured flannels hanging over the basin that are spaced far apart. But in close-ups of the sink they are touching. Also when the chipmunks are playing with the blender there is a tin of "Thai Tea" beside the appliances; but this is only there in close-ups. In wide shots the tin is not there. (00:14:10)
Continuity mistake: When Dave gets back home from Jett Records, he throws the muffin basket that he stole into his garbage can. When he does this, as he throws it into the can it causes the clear plastic bin liner inside to come off from around the edge of the bin. But in the next shot the bin liner is perfectly sitting around the whole edge of the bin again. (00:09:35)
