One day, all the Koopalings, the two Wario Bros., and Bowser were planning to  capture the Mario Bros. They all went their seperate ways to try their own plans.

The one who had been defeated by Wanda in the past set up traps in Mario and Luigi's house, while the one who was the first boss in the SNES version of  Mario is Missing put poison inside their pasta supply. Unfortunately, Mario  found the traps because they weren't hidden too well, and Luigi threw out all the pasta because it was past its expiration date.

Next, the one who appears over the mini-game "Big Top Drop" in the Mario Party 5 article in Volume 174 of Nintendo Power decided to set up Piranha Plants all around the house, while the one with a scar on his face decided to burn the place down. Unfortunately, this killed the Piranha Plants, and the Mario Bros. had left to go sell that  house while it was being burnt down.

Next, the one whose name is last when you put them all in alphabetical order tried to flood Mario and Luigi's new house, and the one who was the first boss in Super Mario World tried to send a heat wave to kill the Mario Bros. Unfortunately, the Mario Bros. were once again out  and about, and the heat wave dried out all the water.

Next, the one who battled in the air in Yoshi's Safari tried crushing the house with a giant machine, while the one who disguised himself as a clown in Nintendo Adventure Books 3: Monster Mix-Up tried making a laser cannon to destroy them. Unfortunately, the machine meant to crush the Mario Bros. crushed the laser machine instead.

Next, the one who gave you a key the first time you beat him in Mario 64 decided to just waltz right in and kill Mario, but was quickly defeated. The only one left decided to sneak up on them, and the Mario Bros, a bit tired from the previous battle and other events of the day, were easily captured.
