I don't remember this ep well at all because I saw it 6 years ago, but maybe some of yu know it better.

It's the episode when it was what's her name's (Koopa's only daughter) birthday. And she wanted all this stuff from the real world. And Koopa ended up stealing the White House and all this stuff. And Barbara Bush was in it. That was my favorite ^^

My other favorite was the one when Toad was raising money for orphans or something like that, but he thought he lost the money. So Mario and Luigi entered a tournament for him. And they ended up fighting Koopa and one of his sons. But Toadstool gave them stars and they won the tournament.

Those're also the only eps I remember of the show. And they're the last two I ever saw, six years ago.
