* It was a good idea for the magical woman to give Mother a fairy daughter, rather than a human one. With the fairy's growing up so fast, Mother was able to raise Thumbelina, watch her get married, and presumably give her tiny grandchildren. Had Thumbelina been a human living a normal life span, Mother would probably have died of old age before her child was fully grown.
** That might have less to do with her being a fairy and more to do with her being born from a flower...
** Continuing that idea; tiny semi-adult? Inconvient, but still easy to take care of. Tiny baby? Accident waiting to happen.
* The reason Thumbelina holds the IdiotBall so tightly throughout the movie? She was LITERALLY [[IncrediblyLamePun born]] [[StealthPun yesterday]].
* The fairy brings the old woman a flower bulb that contains Thumbelina. The fairies apparently come from flowers as well. Thumbelina gains wings at the end of the story just like the other faries. That means that Thumbelina could've been a fairy all along, and the fairy woman knowingly kidnapped her from her people.
** [[ChangelingFantasy Kidnapped]] [[AlternateCharacterInterpretation or given as an orphan to a woman who wanted a child?]]
*** It wasn't a fairy the old woman went to, it was a good witch. She just looked like a fairy, but it was probably a glamour spell, as witches are known to do.
* Mrs. Toad's actions become a good bit more disturbing when you know more about the [[SarcasmMode fine tradition]] of bridal kidnapping.
** The plot in general is a lot more disturbing when you consider that it consists almost entirely of a naive girl being kidnapped from her home and being used and tricked by nearly everyone she meets (even the bird is too obsessed with being a ShipperOnDeck to get her safely home). And a lot of those people want to ''marry'' her, even though they're ''different species''.
* The level of sadism in Ms. Field Mouse and Mr. Toad. Ms. Mouse delivers the news of Cornelius's supposed death in the cruelest way possible, and taunts Thumbelina about it constantly, urging her to sing a "romantic" song for Mr. Mole. While Thumbelina's still going through that, Mr. Mole shows her the corpse of her best friend, treating it like an interesting discovery and happily saying "That's one less bird twittering up there." Also, Mole has bugs pinned to his walls as trophies or decor, and Thumbelina has interacted with bugs. So from the perspective of the non-human characters, Mr. Mole's [[NightmareFuel walls are lined with corpses of dead people pinned up for decoration]], and finds the accidental death of a man he doesn't know amusing. Also, he was holding his wedding ceremony in the cavern filled with dead-body decorations.
