Mario and the gang landed back on Earth after having gotten some Stars from Abandoned Outpost.
Mario: We're doing great, team! We've got 19 stars now!
Toad: 19?! Already?! We're making great progress! Where should we go next?
Before they could decide, three familiar Goombas appeared in front of them.
Green: Hey Mario! Did you miss us?
Toad: Goombas!
Yoshi: Not you guys again!
Green: We are back and we brought some new gadgets! With these, you stand no chance at all!
Blue: Bowser had 3 stars laying around in his castle, so we just snatched one to be even stronger!
Purple: There's no way Bowser will be mad at us after this… right, guys?
Mario: It doesn't matter how strong you goombas get. You're still goombas! So we can still flatten you like any other goomba!
Green: We'll see about that!
The Goomba Bros summoned weapons of their own. Green had a bouncy spring, Blur had a retractable boxing glove, and Purple had spikes on his head.
Blue: We're not the ordinary goombas you're used to stomping.
Purple: Yeah! Let's get 'em, boys!
Mario: Let's a go!
Mario fought Green, Yoshi fought Blue, and Toad fought Purple. Green's bouncing height was higher than Mario's jump, but that didn't matter as Mario stomped Green while he was on the ground. Blue kept backing up as he tried punching Yoshi with his boxing glove, but Yoshi flutter jumped over it and stomped on Blue. Purple had spikes on his head, so Toad had to use a different tactic. He kicked Purple in the face, knocking him back and getting his head stuck in the ground. All three of them were injured and got up groaning.
Green: These guys are using dirty tricks! They must be cheaters!
Blue: Yeah, this is stupid. I don't play with cheaters. What lame-os.
Mario: Oh, shut up! We beat you fair and square! You're just making lame excuses.
Purple: Excuses? You think we're making excuses? Pff, sure we all saw your jump! That's not allowed! I'll tell Bowser!
They all disappeared, leaving a star behind. Mario took it.
Toad: Hey! We've got 20 stars now!
Yoshi: Yeah! We should go confront Bowser. He might have the key we need to unlock that gate underground.
Mario: Good idea Yoshi! Look out, Bowser! Here we come!
