Power-up: The Tanooki Suit. I think the creators were on drugs when they made this. Mario becomes a raccoon, and can turn into a statue? Hilarious.
Level: 4-4 of Yoshi's Island. Marching Milde's Fort. I love the 4-pronged design -- and it requires one to have a solid grasp of all skills in game to pass perfectly. And the boss fight is rather fun to mess around with.
Game: Tetris Attack. One of the most novel puzzle concepts I've seen. Yoshi's Island is a very close second.
Boss (fight): I always liked the boss fight against General Guy in PM[1] for some reason.
Character: Booster from Super Mario RPG. If we're going Main 8 (I'm assuming the Main 8 are the selectable characters in MK64), I'm going to have to go with Luigi.
Enemy: Gargantua Blargg, YI and TA. I can't figure out why, but this is my favorite enemy.
Quote: You idiots couldn't find water if you were fish! ~Booster (might be a bit off) -- as an aside, the quotes I use rather frequently in real life are Bowser quotes:
"Now you know what it feels like to be me. What a great experience!" -- From Mario Party 1
"Confound it, you silly donkey. Just you wait. Just you wait and see." -- Tetris Attack
"Like the moon over
the day, my genius and brawn
Wasted on these fools." ~SMRPG
(Granted, my "brawn" is really only slightly above average, it's more the genius part the suits me)
Favorite game music: Castle Theme from Yoshi's Island
Favorite cameo: I really do not pay attention to such things. Honestly.
That's about all, really. Enjoy.
