+There's actually two waves of enemies before fighting Iggy. The first wave isn't really a wave, though...
Mario, Huey, Edwin and Louis arrive atop...
HUEY: Look, Mario! There it is!
Camera shows...
HUEY: The Topaz Grand Paint Star!
IGGY (voice): What the- you're here, too!? HUWUHWUHWUH! And just after we ambushed the big guy and his girlfriend!
O'Chunks and Nastasia are tied up in the right corner. Nastasia's eyes are covered by a bandana.
O'CHUNKS: I canna' believe I walked righ' inna tha' one! When I get loose, Imma chunkin' the green-haired turtle!
NASTASIA: I'll come with you to that appointment, O'Chunks. After I regain my sight, of course.
IGGY: Get a hotel room, you two! The only way this could be worse is if-
?????: Mario! I've been looking all over this island to pick a bone with you!
A Goomba wearing Musketeer garb drops in from above.
LOUIS: Flying Goombas? Now I've seen everything. By the way, uh... who is that guy, Mario?
Mario thinks. He then shrugs.
MYSTERY GOOMBA: How could you not remember me, Mario! I'm the Goomba who that other Mario damaged. Ooh- I think I still feel it now, just thinking about it.
MARIO: ?
MYSTERY GOOMBA: You ruined my buddies' wheelerific revenge against them?
MARIO: ?
MYSTERY GOOMBA: ...You wrecked the awesomely giant Papercraft I was riding?!
MARIO: ! ...?
MYSTERY GOOMBA: Aw, come on! That one was a freebie! OK- how about this one-?
NASTASIA: Hold on- I know that voice. Perry?
MYSTERY GOOMBA/PERRY: Oh NO. Why are YOU here?!
NASTASIA: Yeah, you were that team player who helped detain the man in green. Even though ...it doesn't matter anymore... I appreciate the spirit.
Mario looks annoyed at Perry over this. Meanwhile, O'Chunks looks sad.
O'CHUNKS: Nastasia...
PERRY: Well, good for you! I moved on to better things, though! I'm working with the Musketeers now! And for my first test- I'll finally get rid of Mario!
A battle with Perry begins.
BGM- Megasparkle Goom... Battle [Original] (Paper Mario: Sticker Star [Recut])
HP: 80
ATK: 10 (headbonk), 2 x 5 (multibonk)
+Every turn, Perry can steal energy from the Partner Meter to permanently power up his next attack by 2. This stacks, by the way.
DEF: 0
After the Perry battle...
PERRY: Don't think this is over, Mario! I'm not forgetting this fight, either!
Perry runs away like a punk.
PERRY: Aaaaaace!
After Perry leaves...
IGGY: Now I know why we didnt bring that guy with us- hes so needy. Any more interruptions from the Musketeers? No? GOOD! AHAHAHAHA! Welcome to the Battle Royal- the last fight of Mario's life!
Several enemies come up into the arena on lifts.
LOUIS: Aw, no, fratello!
EDWIN: We can't take on all of them! Even Aace would find this difficult!
HUEY: You're right! There has to be a better way!
O'CHUNKS: Tha's it- time to unleash a chunkin'!
O'Chunks breaks free from his bonds. He also releases Nastasia of her bandana.
NASTASIA: Thank you, O'Chunks. Now- why dont we you and I pencil in a 3 oclock battle with hordes of the Bowser group?
O'CHUNKS: You're speakin' my language now, Nastasia! CHUNKS AWAY!
O'Chunks and Nastasia enter the foray.
EDWIN: Its nice of them to join us...but even now, we may still be outmatched!
HUEY: Maybe theres some other way to take them all out at once...Lets take a look around this place.
+Regarding the second wave...
+The Goombas are replaced with Dry Dry Pokeys.
+The Spikes are replaced with Clubbas.
+O Chunks is an independent field ally for Mario, with Nastasia trailing the big guy. O Chunks can take 40 HP worth of damage (which is balanced by the fact the normal enemies have their stats altered- mostly, their ATK is lower), yet defeats 1 enemy every 3 seconds. Once his HP is up, O'Chunks faints, and Mario is on his own.
+If Mario can defeat all enemies before O'Chunks faints, Mario gets 1 extra card for every 8 HP O'Chunks still has.
+Regardless, Iggy runs over the weakened O'Chunks, knocking him into the wall behind Mario.
NASTASIA: O'Chunks!?
Nastasia hurries over.
