The train started going faster, but it was to no avail as the Chain Chomps landed on the final car, snatching the back away as they chomped it into pieces. The five Chain Chomps all snarled as Petey growled back at them, the duel going on as Petey held back the Chain Chomps, two of them sneaking past Petey and chasing Bowser Jr. Petey screamed as he knocked out the windows and car walls, tearing apart the final car as it basically broke off. Petey then tumbled into the fourth car, landing on his back as the Chain Chomps bit away at his body, blood dripping off as the hounds were thirsty for vengeance. Vengeance so powerful it... uh... welp, just forget it.
Bowser Jr. was pushing the Eggplantmen and Primids to the side, rushing to get to the first car as quick as possible, with the other two Chain Chomps following him like a homing missile, chomping the Primids and Eggplantmen like twigs. Going through the blue colored second car, there was one car left - the yellow car, which was before the conductor room, where the train engine lied. The train whistled two times as it went faster, of which was helped since the fifth car broke off, a huge fiery explosion engulfing the tunnel as the area shook. Bowser Jr. fell on his stomach, groaning as he tried getting up, when he was pinned by a Chain Chomp, which hissed at him angrily, the other Chain Chomp looming over with drool in his mouth. Junior grinned as he kicked the Chain Chomp off of him, grabbing the other by its tail and spinning him around, smashing him onto the ground as Bowser Jr. jump kicked through the door, landing in the conductor's room.
