Tiny Tim - The title is a reference to the late performer.
The Magic School Bus - Timmy and various germs touring Vicky's body is similar to The Magic School Bus episodes "Goes Lunch" and "Goes Cellular" (where they enter Arnold's body to learn about the digestion system and to cure his carotenosis respectively) and "Inside Ralphie" (where they enter Ralphie's body to find out the cause of his illness and the immune system). Furthermore, when she accidentally ate Cosmo and Wanda, Vicky was eating "Cheeze Pantz", similar to Arnold eating "Cheezie Wheezies" and "Seaweedies" while he ate the bus in those two episodes. Both Vicky and Arnold have red hair.
Snow White - Vicky's kindness portrayal is a satire of Snow White, which was Walt Disney's very first animated movie even the animals helping Vicky clean up the house are a parody of the animals that help Snow White when she needs their help.

Pettiness: I'm Pettiness, that's jealousy
Jealousy: Why don't I have a suit like that.
Pettiness: And this is anger.

Pettiness: You're not from the nervous system!
Timmy: Oh, look it's obsessive convulsive disorder. (Guards and Pettiness gasp) Duh. (Timmy runs back to his shrink suit while the guards and Pettiness are distracted)
Vicky: What?! Cute little animals?! And they're CLEANING?! GET OUT! (Vicky's yelling scares the animals out of the house just as Timmy's parents drive back into their driveway)
