Took the World 5 cannon to World 8 and beat the game.
THIS
IS
DELICIOUS
I've gotta do spoilers!
[spoiler]
Okay, so, it's already cool enough that Jr. HIJACKED BOWSER'S Koopa Klown Kar! On the airship! Now,
EPIC FINAL BATTLE
So you trounce Bowser once, but you're missing the last Star Coin. You run under him, hit the switch, there's Peach.
WRONG. It's Kamek! And she Rump Commands Bowser! The Final Battle is an auto-scrolling race against Bowser's wrath! He's tearing up the place, spitting house-sized fireballs at you, swiping his claws and destroying his castle trying to get you! This plays a lot like the Megaman Tribute entry that Vixy helped with. Then at the end, there's a HUGE switch, that destroys the castle floor, drains the lava, and takes Adrenaline Bowser with it!
Standard ending, Luigi and the two Toads arrive in hot air balloons, Luigi opens the...basket door?...for them and bows, Peach takes Mario's hand (
), and sail off into the sky...leaving Luigi behind, Luigi hitches a ride with the Toads.
After all that, it shows Mario and Peach in the balloon, and Peach asks Mario if she had ever told him about "that secret world".
Now, I know DARN WELL what that means! But, it just so happens, you unlock World 9 afterwards.
Final scene, Larry's crawling on the ground, Jr. condescendingly points toward the other Koopalings, instructing Larry to help get Bowser+ back on his stomach or feet, whichever he can do.
THEY DO! Bowser wakes up on his stomach with a loud THUD! Everyone rejoices!
...but...uh...his little episode causes the ground to shake, and the front end of the castle falls on him...
[/spoiler]
Totally worth EVERY frustrating moment trying to get all the Star Coins (well, where I played)! Good thing that cannon was there, though; I was getting tired of OBSTACLE COURSE again and again and again and again.
Even if this game doesn't have replay value (which, I think it might, but only as much as NSMBDS, which is low), it was so worth the experience!
Now, onto that...secret world!
...so using that as a pickup line...
