"You may remember the Boo Buddies from Super Mario Bros. 3. This time there's a whole horde of them! And amongst them there's a huge spook called The Big Boo. But don't worry, if you look at them, they act shy and turn away. Cute, aren't they? But watch it...they're dangerous!" -Super Mario World Instruction Manual

"The giant Ghost House host isn't very hospitable. Use the Blue Blocks for ammo. Throw them up at him to send him haunting elsewhere." -Mario Mania

"Now here's a real back-biter. Bigger Boo closes his eyes and almost fades into the stonework when Yoshi looks at him. Turn around, though, and he'll swoop down for a dino dinner! Say "Boo!" to Bigger Boo by making the fanciest collection of bank shots this side of the world billards championship." - SMW2 Player's Guide

"The self-proclaimed Tower of Terror thinks quite highly of his abilities as an apparition, but he's not likely to scare anyone with his pranks. Mario can use his patented Boo-stomping method to end the Big Boo's feign of terror. Face away from him, then Pound the Ground when he's close. Three stomps do the trick." - SM64 Player's Guide
