Phineas and Ferb in Wonderland

Sort of like a sequel to Wizard of Odd.

Story
Phineas, Ferb, and Candace follow a nerdy white rabbit down a rabbit hole and into a mysterious world. There, they meet two identical bullies who tell them about the Red King and Queen taking over. Perry is sent into the world to fight the king. Along the way, Phineas, Ferb, and Candace run into Stacy the Cheshire Catgirl, who tells them that they must free the White Queen in order to defeat the red one. And they also meet the Mad Hatter, the May Hare, and Vanessa the Python.

The "Too Young" Line
Candace: "Did that rabbit just talk?"

Phineas: "I think. I think it did."

Phineas: "But isn't that a little redundant?"

Stacy the Cheshire Catgirl: "Yes. Yes it is."

Mad Hatter: "Are we having fun yet?"

May Hare: (Sarcasticaly) "Sure. SURE we are."

Where's Perry?/Oh, there you are, Perry
"Hey, we forgot about Perry!" -Phineas.

"Perry, there you are! Hey, nice hat." -Phineas.

Whatcha Doin'?
Tweedle-Dee/Tweedle-Dum: "So, whatcha doin' here?"

Memorable quotes
Candace: "I thought it was supposed to be a caterpillar?"

Vanessa the Python: "Bugs creep me out. Snakes are a lot cooler."

Phineas: "That's a story-changer."

Red King: "Um, forgive me for this, honeybunches, but aren't we supposed to do like a lawsuit thing in the court?"

Red Queen: "Why would we perform a lawsuit on the royal tennis grounds?"

Red King: "No, I meant the big, brown room with all those seats in the castle."

Red Queen: "Oh, THAT court."
