He builds some rides and shops, but also faces some problems such as thefts, unhappy staff and guests, and lack of toilets. He then switches to a creative mode where he can build anything he wants. He experiments with different rides, terrain, water, special effects, and mascots. He makes some ridiculous and dangerous roller coasters that launch the cars into the air or into the water. He also fills the park with cows and robots. He ends the video by saying that he had fun but he is not good at the game.
