King Boo[]
- "Blue overalls...Cute button nose...White gloves...Mustache?!? MARIO! HOW DID YOU GET OUT OF YOUR PAINTING!?!...Wait a minute, your shirt and hat are green. It's just Luigi!"
- "Ah, I could just stare at this 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."
- "Anyway, who would actually believe that mansions get given away in contests? Talk about stupid! What do they feed you Mario Bros. 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! BLUH HUH HUH HUH!"
- "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 [makes noise] vacuumed up all my friends!"
- "Don't imagine I'll flee! I'll fight you like a true Boo! Now, join your brother... INSIDE THE PAINTING!"
Luigi[]
- "MARIO!/MARIOOO?/Mario?"
Mario[]
- "Get me outta here!"
- "Hey, Luigi! What's the hold up!"
- "Hey, Luigi!"
Professor E. Gadd[]
- "I'm getting too old for this ghost-catching tomfoolery."
- "Anyway, nice to meet you. I'm Professor E. Gadd."
- "I swear, this house seems to have more and more ghosts every day!"
- "Alright, youngster! Look lively! Follow me, posthaste!"
- "I've been living here since I was a lad of twenty or so, and I'll tell you: That mansion just appeared here a few days ago! The spirits have fooled you!"
