The train conductor, a red timid Cheep Cheep, gasped as he hid in the corner, with Bowser Jr. taking control of the train, turning the train towards the right direction, heading south. The Chain Chomp remaining on the train growled as it shook its head, rushing towards Bowser Jr. and lunging towards him when its tail was bitten by Petey Piranha, who was triumph over the three other Chain Chomps. The Chain Chomp whimpered as Petey ate it, letting out a satisfying laugh as he casually walked into the conductor's room.
The train conductor trembled with fright as the four remaining cars broke apart, bursting into huge flames that engulfed the tunnel once more as Bowser Jr. made what was left of the train to go faster, with Petey looking out for trouble. The train exited the tunnel, and was way higher than expected... it was literally high in the sky, within the clear blue sky and the white puffy clouds as the train was riding on wooden tracks. The tracks started shaking as it was being broken apart, the train shaking violently as the entire structure was crumbling at the seems. Bowser Jr. and Petey Piranha both looked at each other as they held onto each other, screaming as the entire structure broke apart, the train falling several stories below as the physics and laws of gravity was being broken.
Dialga and Palkia were having tea with Giratina as the three dragons turned around, watching the train containing Bowser Jr. and Petey Piranha fall down. Bowser Jr. snapped his fingers as he jumped on Petey's back, pointing at the sky. Petey Piranha gasped and nodded as he extended his leaves, jumping off as the train continued falling, with the train conductor screaming as he was left on the train, flopping for his life. Bowser Jr. and Petey Piranha looked at each other, laughing as they gave each other high fives, with Petey flying upwards towards the bright, shiny sun, their adventure full of action and excitement.
...But that was only the beginning...
