Marcus is scheduled to take an exam on Kristy's birthday. He goes to his new friend Thomas for help. Thomas agrees to take Marcus's sister and mother out for the day for Kristy's birthday and also agrees to have dinner at their house the day before to get acquainted. Thomas does much research and plans out the perfect day for the little girl's special day. The next day, Thomas picks the two girls up in his fancy limo with his nice white tux on ready for a grand night out on the town. Kristy is more worried about having fun in her own way though and persuades Thomas to let them go to the arcade. The three find themselves at an amusement park where Thomas reminisces the time he spent with his own mother. Their night is interrupted by a surprise attack from a large Citrimon. Gaomon emerges from Thomas's Digivice and Digivolves to Gaogamon. Gaogamon hurls Citrimon into the air, creating an amazing firework display as Citrimon's DigiEgg falls to the ground below. Back home, Marcus's family in addition to Thomas, Yoshi, Lalamon, and Gaomon share a nice birthday dinner.
