Koopie Koo

"Koops... You're OK, right? You promised me you'd come back OK..."

- Koopie Koo

Koopie Koo is Koops' girlfriend. She appears in Paper Mario: The Thousand-Year Door. Koopie Koo pleads Koops not to join Mario's team and go slay Hooktail to avenge his father, Koopley, but Koops is adamant about his plans. She loves Koops no matter what; he need not prove anything to her in the game. She adores him despite the fact that he is weak, but Koops wants to change and become a hero. She becomes so mad that she withdraws into her shell, and fires herself at Mario and Koops. However, she consents to his leaving for the journey. After Koops leaves Petalburg with Mario, she waits for Koops to return home as a stronger Koopa. She has a tendency to be somewhat overprotective of him at certain times, similar to Lakilulu from Paper Mario.

Later in Mario's adventure, he receives an e-mail from Koopie Koo, who expresses her loneliness without Koops and how an odor from Koopley, presumably from spending years in Hooktail's belly, is grossing her out. She is also the answer to a question of the X-Naut Fortress Thwomp, who asks the name of the girl in Petalburg who is waiting patiently for Koops to return.

E-mail
Dear Mario and Koops, I hope you two are doing OK. I have to admit, with Koops gone, I haven't been doing very well. I get lonely, and I go into Koops's house, and I smell that Koops smell. I guess it's your cologne or whatever, but it makes me so sad... I'd gotten used to your smell, Koops...Oh! And the thing is, your dad, Koopley, has his own smell, and it's...weird. I think maybe it's the smell of Hooktail's gut. That's...disgusting. Now I grossed myself out. Oh, and since he's gonna be my dad, too, someday, I'd better get used to that smell, huh? ...Oh! What am I writing? I'm so embarrassed...but I'm sending this anyway! Hee hee hee! Love, Koopie Koo
 * Miss you!

Tattle

 * "That's Koopie Koo, a local Petalburger. She seems to be Koops's girlfriend. Gosh, she's really cute...and she seems to have a good head on her, too. Thing is, because she's smart, she kinda mothers Koops a little bit... I guess it's a complicated relationship. But then again, what relationship isn't?"

Trivia
