After Jerry Gourd plugged the plug under the table into the outlet to power up the ship, the lights turned from yellow to white, but at the shot of Scooter, the lights are still yellow and then switch back.
Despite being shown with only a single tooth in prior and subsequent episodes, Larry is briefly seen with both top and bottom teeth when he attempts to eat a candy bar off of his helmet.
The USS Applepies is not moving at all (in space), and is supposedly out of power. It should have been moving at whatever speed it was moving when it lost power, because there is no friction in space (so it couldn't have slowed down). However, the segment is obviously not intended to be realistic, as the the vegetables enlist a child to fix the ship, the gourds survive in the vacuum of space, and the entire ship is powered by a plug. It is also possible that Junior imagined everything.
In some shots, the distance between Flibberolu and Jibberdilot shorten up just to show the objects the towns are lobbing at each other. This is intentional by the animators to exaggerate the town sizes as well as the curved trajectory of the lobbed shoes and pots, otherwise the two towns would have been too small to be noticeable on the screen if the battles were shown to scale.
The USS Applepies can't move out of the way of the meteor because it is out of power. Bob and Larry's ship is shown to be fully functional, however. If Bob, Larry, and Junior were able to enter the Applepies from it, it would have to be latched to the Appliepies. So why not just use the smaller ship to get the Applepies moving?
At the beginning Larry has a shoe on his head and Bob says this is because he'll be portraying a resident of Flibber-o-loo. However, he hasn't been wearing props he has in the show on the counter top in any previous videos, and he even has an oven mitt stuck on his head the entire time despite his character having a chocolate factory cap in VeggieTales: Rack, Shack & Benny (1995).
