In the pie factory, Lucky, Cadpig, Rolly, Spot, Horace and Jasper are seperated onto two different tracks. Rolly gets placed onto Horace and Jasper's track, but in the next scene, he's on the same track as the other main pups.
During the roller coaster ride in the pie factory, Lucky, Cadpig and Spot get covered with pie fillings, powdered sugar and whipped cream, but they're perfectly clean in the next scene.
At the end of "Invasion of the Doggy Snatchers", Spot suddenly turns green as the other chickens are cheering for her.
Spot: (thinking the pups are aliens) Stay back! I know karate! Okay, so I don't know karate, but I can dance! That's gotta count for something, right?
Spot: We're lost! I knew it! Doomed! Doomed! Just one more chicken on a milk carton!
Ed: And be sure to buy your ticket for the ten-thousand...oh, I've only got eight fingers!
Rooster: What are you going to do? Walk up to that barn holding a crock pot and say, "Hi. Are you guys aliens?"
(Scene skips to Spot at the front door of the barn holding a crock pot.)
Spot: Hi, are you guys aliens?
(Spot rockets up to the ceiling of the barn and gets her beak stuck.)
Cadpig: She did it again.
Lucky: I'll get the crowbar.
Cadpig: Personally, I'm drawn to the symbolic journey of the roller coaster carrying you through life's ups and downs... till you puke.
Spot: Ha! There's no way you'll catch me on any of those death thrillers! Do you know how many people are manged every year on merry-go-rounds?
Lucky: Uhh... none?
Spot: Exactly! A tragedy is long overdue.
Jasper: Hey! Stop eating my pie!
Spot: I think I froze my giblets!
Lucky: Hey, chill out!
This marks the third time in the series Lucky's fur is a different color.
When Rolly demonstrates how he's going to eat at the pie-eating contest, the way he eats them is in some way reminiciant to Pac-Man, an early 1980's video game.
