Paper Mario 2 The Thousand-Year Door Easter Egg - Kolorado's Dad From The First Paper Mario

Go to Hooktail's castle in chapter 1 of Paper Mario 2: The Thousand Year Door. Go inside the castle and go into the room after the one with the Paratroopas. When Koops notices the skeleton of his supposed "dad," read the note and at the end it will say: "My last words go to my son, Kolorado: I love you, and I'm proud of who you've become." If you go back to Petalberg, try with Goombella all you want, but no one there is named Kolorado. That's because it's the Kolorado from the original Paper Mario!
