Arnold (Japanese: アーノルド Ānorudo) can be seen driving around My City when the owner builds the Tower. Arnold is a professional racer and claims that he is faster and that nobody can beat him. However, his arrogance gets him into an OK ranking, 8th - 10th most likely. He's probably a friend of Roberts. It is unknown where he originally is from.
- "Ha ha ha!! I'm the fastest racer! No one can beat me! Did you see that big tower? It's the tallest tower! The tower and I are the best in the world."
- (Before recruiting him) "Anyway, I heard you race too. Anyone who teams up with me is lucky! What do you think? Don't you want to team up with me?"
- (Declining his request) "What, are you mad? I said, I'll team up with you. You are so strange..."
- (Recruiting him) "OK, there you go! I won't allow you to be the last in the race! I'll try harder than your old teammate!"
- (Whilst on your team) "Hey, I didn't know you were a fast racer. I'm surprised! I, Arnold, the world's best, will give you credit."
- "See you!"
