Super Mario-kun Volume 2

Super Mario-kun Volume 2 is the second volume of the manga series, continuing the Super Mario World story arc that began in the last volume, while the last chapter is a collection of quick stories about Mario's previous adventures (from Donkey Kong to Dr. Mario). In this part, Mario, Luigi, and Yoshi skip Vanilla Dome but go through the Twin Bridges and the Forest of Illusion, and ends with a search for a Star Road. The Koopalings Ludwig and Roy are encountered.

Stage One
変身カメック！！　にせヨッシーで大活やく！？ (Kamek's Transformation!! Fake Yoshi makes a big difference!?)

Yoshi finds behind a rock a giant pile of Berries. Yoshi informs Mario and Luigi that he's going to eat those, while the two brothers make snarky comments about his problematic hunger. Ignoring them, Yoshi goes to eat the Barries, but they transform into Koopa Troopas: it's a trap and Yoshi finds himself tied and hung to a block. Kamek appears and, congratulating the Koopa Troopas, transforms Yoshi's face into a Fuzzy, then takes his place and returns to the Mario Bros.

The two brothers do question Yoshi's oddities, from his new glasses to his personalities, but they have better things to think about, like a large troop of enemies that is coming to them. During the following battle, Mario and Luigi notice that Yoshi is yelling at the enemies for hurting them and become wary of him. Mario takes a bunch of Goombas and asks Yoshi to eat them. Kamek tries to avoid doing that by telling that he's full, but that makes the brothers grow more suspicious of him and forces the Goombas and a Pokey in his mouth. Then they ask him to breathe fire and Kamek tries to use a cardboard cutout to trick them, but fails.

Kamek manages to earn more time by pointing out to a Passin' Chuck, to which he almost speaks to. The Chuck kicks a giant football to them, but Mario grabs Yoshi by his tail and uses him as a baseball bat, pitching back the football and sending it back to the Chuck, defeating him and Yoshi. With Kamek knocked out, his magic disappears, revealing the disguise to the brothers, who run back to find his friend. They immediately find him: while they were fighting, Yoshi ate his Koopa guardians and used the fat he gained to break the rope that restrained him, but still has a Fuzzy head.

Stage Two
大ピンチ！！　巨大メカクッパをやっつけろ！！ (Big Trouble!! Defeat the Giant Mecha-Bowser!!)

Bowser is furious with his minions: they can't stop Mario and his friends, they try to calm him down by disguising like Princess Peach, while the real Peach mocks their failures. Full of rage, Bowser gets to know that Mario and his friends are just walking in the Vanilla Dome and give order to activate "it", making sure to press with all his might the ON button.

Inside the dome, Mario and Luigi are playing with the echo, until they realize that a metallic sound is getting closer. Suddenly, in front of them, a gigantic robot shaped like Bowser, the Mecha-Bowser, appears and attacks them. The Mecha-Bowser starts to try to kick them, but they manage to dodge its feet and realize that it's also slow, so the heroes try to leg it, but the Mecha-Bowser spit metal boogers at them from the nostril. Yoshi is hit, but Mario grabs him and uses him as a club to hit the robot, making him dizzy. The robot then uses some arm-drills to hit the three, but drills the ceiling of the cave.

The cave is flooded with water and Dolphins from the Vanilla Secret 3 level. While Mario is stopping Yoshi from eating the Dolphins, he asks them to take them to the top of the dome, outside. The Dolphins help them rise the new waterfall and take them to the top of the dome, where Mario seals up the hole, trapping Mecha-Bowser in the flooded cave. As soon that Mario stops Yoshi from, once again, eating a Dolphin, the Mecha-Bowser emerges from the ground and returns to the attack.

With one fist swing, the heroes are knocked down. Mario grabs the only power-up he has, a P-Balloon, and becomes Balloon Mario, fleeing in the sky. Between the clouds, Mario finds a 3-Up Moon and, grabbing it, becomes Moon Mario. With his new powers, Mario flies at Mecha-Bowser, unfazed by its lasers, grabs a Cape Feather from the Item Storage and uses it to tickle Mecha-Bowser's nose. The robot sneezes, puking out all of its mechanical components, and shuts down. The Mecha-Bowser gets rebuild by Mario and his friends into a Ferris Wheel, while Bowser is crying for yet another failure.

Trivia

 * In chapter 10 title page, there's a shot of Cookie Mountain in which the hill have a band-aid that the game explained being caused by the crash of Ludwig's castle, but the castle, in the manga, doesn't crash on the mountain, meaning that band-aid shouldn't be there with these circumstances.
