I released this before, then did a casual playthrough, only to find that the release wasn't as good as it could be. I decided to polish it up some more and rerelease for C3.
After saving Peach from Bowser on the Starlight Islands, our heroes decided to take a vacation in the Kola Kingdom, a kingdom whose only connection to the Mushroom Kingdom was a warp pipe in its frigid Winter Valley region. The pipe is kept open by 7 Star Keys.
While relaxing on the beach, Mario received a frantic call from Toad saying that the Mushroom Kingdom was under attack by monsters. Moments later, he received a boastful call from Ludwig von Koopa. He and his siblings had stolen the Star Keys. Mario immediately knew what he needed to do.
Mario and Luigi begin their adventures in this tropical paradise, which is being spoiled by Ludwig and his forces.
Wendy O. Koopa has taken over this fungus-filled grassland and laid claim to its tasty mushrooms.
These desert ruins have been overrun with fire-spitting plants, sentient cacti, and some turtles who like to blow themselves up.
Iggy Koopa has hidden the fourth Star Key in this forest. Foul-tempered caterpillars, Lakitus, and deadly sap await our heroes here.
MISTY MOUNTAIN MINES
These caves are full of sparkling crystals, as well as Koopas, Swoopers, and Buzzy Beetles.
This entire city is made of pipes, and where there are pipes, there are bound to be Piranha Plants. Our heroes are bound to be pretty wet by the time you make it to Larry's Castle.
Brr! It's cold here. This wintry wonderland has been spoiled by Koopas and other nasties. Be careful on the ice.
The bros. have finally made it back to the Mushroom Kingdom, only to find it transformed into an industrial wasteland. Could Bowser really be behind this?
What's this? The brothers have uncovered a Star Warp that has taken them to the moon!
"Experience, lad. You should learn to appreciate it."
