The Wacky Wario Bros.: The Welcome Invitation is the twenty-fifth episode of Season 3 and the one hundred and twenty-fourth overall to be uploaded by SMG4.
This is the first episode of the The Wacky Wario Bros. series. It was aired on May 19, 2013.
The Wario bros. or idiots come across Peach's castle, thinking that they can claim as their own and have their own mansion. :O what could possibly go wrong?
Later, Waluigi had the idea that he and Wario enter the castle from the roof. They find a cannon and launch Wario to the roof, but he hangs on for dear life on the edge. Waluigi tries to catch Wario, but it is not a good catch.
They somehow make it onto the roof and plan on how to get through it. Waluigi tries using a Bob-Omb to blow up the roof, but it doesn't work. He tries throwing a paralyzed Wario through the roof, which briefly worked, only for Wario to be launched by a Chain Chomp up the way he fell.
Just when Waluigi was about to give up, Wario finds a way through a door at the emptied moat. After moving through the tunnels, they find Yoshi. Wario rides on Yoshi right through a wall, and he and Waluigi are in the castle lobby. However, they are shortly discovered and kicked out by Mario.
