Disclaimer: I don't own Alice in Wonderland. I suppose Lewis Carroll does. This is a fanfiction.
There she was now at her right size. There she was upon a house with a Frog-Footman and a Fish-Footman in front. The Fish-Footman had an invitation for the Duchess. He delivered it to the Frog-Footman. Alice observes transaction
"What a bunch of rubbish"
Alice thinks to herself after a failed attempt to get inside by proper manners. She goes in anyway for the door was in fact unlocked. Surely she was smarter than Goldilocks but regardless staying outside seemed awfully boring. In the house she meets the Duchess, The Cook, The Baby, and The Cheshire Cat
"Hello cheshire puss"
And indeed she did say that for all the lot of good it did her in the situation. The Cook was throwing dishes and making a soup which has too much pepper, which causes everyone but the cook and cat to sneeze. The Duchess gives the baby to miss Alice
"Get out of here, you and your younger brother"
Alice is confused by this but she does leave the house. Afterwards she checks on the baby.
"You make an ugly baby but you make a handsome pig"
In fact this was quite true true so in any case over the course of mere moments the baby boy becomes somehow or another transformed into a baby pigboy and Alice herself transforms into a cute piggirl for whatever reason Wonderland decided this was supposed to be.
"I will keep this baby"
Her new brother oinks in agreement. Alice oinks and rubs snouts with what from then on forever more her bro. Alice and the baby, the two piggychildren of the Duchess. Alice is a piggirl, her clothes fitting fine sans shoes and socks now but nontheless she lives happily ever after. THE END
