"What's that he's got on his back!? It's E. Gadd's Poltergust 3000! Everybody scram!"
"I don't plan to give up my favorite decoration. I like Mario where he is."
"Aahh, I could just stare at my Mario painting for hours!"
"It's true what they say about fine art... it takes utterly refined sensibilities to truly appreciate it!"
"The way you plead for help, Mario... I find it so... satisfying. Perhaps that is merely because I remember how much trouble you've caused me in the past."
"... Seriously, though, who would actually believe that mansions get given away in contests?! Talk about stupid!"
"What do they feed you Mario brothers anyway, gullible soup?"
"Your brother came all this way just to get turned into a painting... It's just terrific. However... This Mario painting looks lonely... I must have a Luigi painting as well! Then my gallery will truly be complete! Bleah HA HA!"
"I'm not afraid of you, fool! I fear only that infernal Poltergust 3000 you carry on your back! Stupid machine!"
"But I am a KING among Boos! I swear it, I shall fear no mere house-cleaning device!"
"I must say... I despise the way you SHWEEERRPP-SHLOOOOP-WHOOORPP-SHLEEEOOORG-vacuumed up all my friends!"
"Don't imagine that I'll flee... I'll fight you like a true Boo! Now join your brother... inside the painting!"
"So your name's Luigi? I think our paths were destined to cross. Well met, Luigi."
"If I told anyone else, they'd have me committed."'
"So you won this mansion in a contest you didn't even enter? Sounds pretty fishy to me... So you really believe the mansion exists then. Well, I've been living here ever since I was a lad of twenty or so, and I'll tell you... That mansion appeared here just a few days ago! The spirits have fooled you! I don't know if it was a dream or an illusion or whatnot, but I surely wouldn't be too happy winning a haunted house. Now that I get a good look at you, I just remembered a guy with a red hat like yours walked up to the mansion without stopping to chat and he never returned. Was he a dream too? What? That guy was your brother?! That's horrible! He would never stand a chance against those ghosts without my help! You have to go after him!"
"Outstanding work! You're like a leopard on the hunt!"
"You stalk Boos like a master! Hail the fearless Boo hunter!"
"Did you see that Boo just give up at the end, Luigi? Your reputation is spreading!"
"Well done, Luigi my boy! This time I have a special bit of information for you! Hey, since you're cleaning the place up anyway, it wouldn't hurt to help out the plants in the mansion. You know what plants like, don't you?"
"Well done, Luigi my boy! This time I have a special bit of information for you! Ghosts other than Boos will not appear in the direction you're looking, so you'll have to sneak up on 'em backward... but I bet you knew that already, heh!"
"Well done, Luigi my boy! This time I have a special bit of information for you! You've seen some small ghosts other than the Boos, haven't you? Well, I'm pretty sure they're ghosts freed from the paintings of the ghost artist, Van Gore. I had a passel of trouble the first time I captured him... I know that artists strive to give life to their canvasses, but this guy brought ghosts to life every time he picked up a brush!"
"The tiger creeps up behind its prey... and strikes like lightning!"
"Tip-top, Luigi! You remind me of myself at your age..."
"Ho! You're on FIRE, Luigi! ON FIRE!"
"You give those Boos what-for, Luigi!"
"Unbelievable! There's no stopping you, Luigi!"
"You're busting out all kinds of wild techniques today, Luigi!"
"Heh heh. Well done, Luigi!"
"Fantastic! Way to go, Luigi!"
"Tonight I’ll make an old family recipe. Pickled dandelions with barnacles in a diesel marinade!"
"Boo hoo hoo! Where did you go Mario? Waaaaaah! Wah!"
"Wah...Wow! It's Luigi! You finally made it! Oh, joy! Thank goodness! Me? Well, Princess Peach asked me to come here to look for Mario. He left when he heard that you'd won a mansion, and he never returned! Th...then when I arrived here, the mansion was full of ghosts and I didn't see Mario anywhere, and I kind of freaked out a little, and I didn't know what to do!! It's been awful! Please, please, please, you HAVE to help me find Mario! If he doesn't get back, you have no idea how upset the princess will be! She'll flip!"
"I wish I could do something to help you.. Wait! I've got it!"
