Vicky has a pet cat, dog, hamster, fish and a parrot. Of all these pets, only Doidle is seen in later episodes when the rest of Vicky's family appears, and even then, his appearances are rare.
First time we see the vet doctor, Dr. Snipowitz, and Vicky's dog, Doidle. Dr. Snipowitz would later reappear as an actual doctor, now working inside a run-down hospital.
This episode inspired the level, "A Dog's Life" in the video game, Breakin' Da Rules. The main differences is that Timmy becomes an actual dog, colored brown and with Timmy's pink hat. The player must avoid Tootie (who has fallen in love with the dog because she wants one of her own and it resembles Timmy) while finding a way to make himself undesirable to her by bathing in mud.
This episode marks the only appearance of Wanda's friends.
This episode reveals that Doidle could possibly have a personality just like his owner: He is a jerk who caused most of the trouble in the episode for fun, not because he was simply a dog who didn't know better. Doidle appears to be sentient and the reason he wanted to stay in Timmy's body was so that he could be a human and have opposable thumbs. This makes Doidle's fate in this episode (and his unhappy look at the end) all the more alarming. In later episodes, Doidle always growls at Timmy and hates him, meaning that he remembers and possibly blames Timmy for what happened to him in this episode.
Vicky's house in this episode is a different color than its appearance in Oh Yeah! Cartoons episode, "The Fairy Flu", but it has the same front porch design. Her house would be completely redesigned in "Boy Toy" and subsequent appearances, but with the same color scheme.
Wanda's quote in this episode, "Well, what's the matter, Big Daddy?" would possibly be a reference to the name of her own father, Big Daddy, who would later appear in Talkin' Trash.
Wanda's phone number is 555-8180
In Transparents, it is revealed that fairies can go through objects, however, in this episode, Wanda smashed herself against a lamppost.
Cosmo: Ah, the great outdoors, and no wife! Ooh yeah, I'm gonna swing, daddy-o! I'm gonna call on my old friends! (while leafing through book) Let's see, Wanda, Wanda with a little star next to it, Panda, no that's Wanda with a smudge on the 'W'. I... I... (while crying) I miss Wanda!
Doidle (as Timmy): Food! Food, food, food! (he devoured the cereal face first)
