Kana has just come out of the forest from hunting with some friends and is looking for a place to sit down until she found the statue of her mother, with a crudely drawn mustache and glasses. Kana grabs a steel katana and slowly walks towards were a bunch of noise was coming from only to see that a weird turtle like creature with a spike shell was drawing on her statue. Kana out of rage shouted out: "HEY YOU! TURTLE THING!" causing the creature to fall off the statue because of being startled. The turtle replied, "You have a problem kid?", Kana a bit frustrated yelled out "Why are you drawing on my statue? My papa will be very mad if he finds out you did this!". The turtle replied "Well this place now belongs to me! Bowser Jr. And my daddy will eat you and yours for lunch if you try to stop me!" as he said this, he jumped as a little mech appeared while Kana got into a combat stance.
