Nose Marie and Buster weren't suppose to be present when Holly and the other Pound Puppies secretly expose Katrina's scheme to the Belveshires. When the camera cuts to the wrecked Stoneheart Condominiums model and Howler sneaks up to the TV, Buster can be seen following him, but when the camera cuts to the TV, Buster isn't present. Also, when the camera cuts to behind the couch after Katrina has been denied of the Belveshires' money, Nose Marie can be seen, in place of Bright Eyes.
Nose Marie isn't suppose to be present when Holly and the other Pound Puppies secretly expose Katrina's scheme at the Belveshires' mansion. When Brattina falls down after being shoved by Katrina, Nose Marie can be seen with the other Pound Puppies and Holly flying out of the Stoneheart Condominiums model and land behind the couch.
In one scene where Katrina accidentally shoves Brattina carrying a model of Stoneheart Condominiums, Brattina cries "Whooa, Mommy!" and you can see Katrina lips move at the same time, which means that Katrina's lips weren't suppose to move while Brattina cries "Whooa, Mommy!".
