Those unofficial quotes are very funny, like Yoshi feels like eating humans. Here's a lot of them:
Yoshi: Ghost!
Peach: Ghost!
Daisy: Ghost!
Luigi: Ghost!
Mario: Ghost!
Bowser: Ghost!
Wario: Ghost!
Waluigi: Toast.
Birdo: Ghost!
Geno: Ghost...
Mallow: Ghost!
Bandit: GHOST!
Shy-Guy: GHOSTS!
Goombas: Ghost!!
Koopalings: Ghost!!
That's a whole lot of ghosts (or should the game says "Boos") out there! Have another:
Toad: Thank you Mario, but Luigi is in another castle!
Mario: What!?
Luigi: That's a whole lot of succotash!
Wario: Is your name Bomberman?
Bandit: I think I'm gonna be sick! *He pukes on Yoshi*
Mario: Is your name Mr. Spinach?
Luigi: I'm not a spinach!
ZIPPO: "Clowns Crocodiles Teeth Burgers Brains Bananas Bones Pies Whiskers Fleas Smiles Ninjas Astronauts Robots Frogs Freckles Garbage Flies Snakes Cakes Pancakes Flakes Bolognas Onions Mushrooms Peppers Spinach Succotash Breakfast Mosquitos Antennas Helmets Gloves Shoes Bombs Bomberman Max Louies"
Note that ZIPPO is a fan-made character and a robot.
Wario: I'm going to eat a lot of breakfast!
Bowser: Great, just great. Now I look like the huge, mighty king of GUYS WHO TALK TO A BOX OF FLYING BOLOGNAS!
Luigi: I'm allergic to Pokémon HeartGold and SoulSilver!
Mario: Must be a beehive nearby, and when there's bees; there's waffles smothered with honey!
Donkey Kong: I'm allergic to bananas!
Bandit *singing*: My name is Hacha Chacha, and here is my spiel, a diabolical plan with lots of appeal. Spreadin' out bananas far and wide, and fixin' up the folks for a slippery slide!
Wario: Bombs! Next to Bomberman himself, they're my most unfavorite things!
Daisy: Thank goodness my name is not Princess Flower, Violet or Rose.
Bowser: Mario! More mushrooms!
Mario: Im-a goin' to play Pokémon Black and White!
Bowser: Get back here, Geno! Don't you know hot peppers are good for you?
Yoshi: Brain! Hack!
Mario: I don't have any brains left as they are.
Luigi: Since when a Mario game stars Bowser as a mascot? Meta Knight and Sonic met together? Where is he at? The Nintendo Logo is supposed to be in the bottom of the box, not flying in the middle of nowhere! Plus, Bandit from Yoshi's Island is also in the middle of nowhere in "Super Bowser: Kojiyama Edition".
Bandit: That garabge and flies stuff is making me sick and puke!
Mario: I like to order some pizza, please?
Luigi: Here Wii go!
Yoshi: Popsicles!
Wario: Brains!
Daisy: Chocolate bars!
Peach: Cheeks!
Wario: Cheeks!
Bomberman: Mmmmmmm!
