Rex and Ace suffer from insomnia during overnight construction while Max and Chomp sleep soundly, sparking a conflict between the two groups. Meanwhile, an Ankylosaurus exhibiting similar sleeplessness appears in a Japanese subway station. The D-Team, accompanied by Ursula, Zander, and Ed, attempts to capture the dinosaur. However, Rex and Ace become separated from the main group. Ed summons Tank to assist, but Zander’s Dino Swing activation allows the Ankylosaurus to use its Mole Attack to defeat the robot. After Ace is also hit by the Mole Attack, he manages to defeat the Ankylosaurus, enabling the D-Team to secure the creature. Following the incident, Max and Rex reconcile and restore their friendship.
