Cool concept, if you are wondering who Zanda Cross is...Well, it originated in "Doraemon: Nobita and the Steel Troops"
here's a little plot info from Wikipedia
"The movie's plot involves Nobita, who throws a temper tantrum because he wants a really large RC toy robot in order to upstage the rich kid, Suneo, who has been showing off the new robot that his cousin made. His fit makes Doraemon angry and being a hot Japanese summer, he goes to "cool off" at the North Pole with the Anywhere Door. Nobita follows him there after he's gone for a long time, and discovers a strange bowling ball-like orb which starts blinking with a pulsating light, and summons what looks like a giant robot´s foot. After sledding down the hill on it and having it crash into his room through the Anywhere Door, the bowling ball follows him home through the door and another robot piece falls into his backyard.
