Successfully complete the game to unlock a blue hat for Parappa.

After you get the yellow hat, push X to go to the title screen. Once everybody is standing on the screen, use the right-analog stick to cycle between hats. Hold the stick down on the color hat you wish to have and press start. Your hat will be that color.

The game places Parappa's neightborhood at the same time of day indicated by the PlayStation 4's time setting. For example, if you set the PS4's time to 11:30 a.m., it will be bright and sunny in the game. If it is 7:00 p.m., it would be sunset. If you set the time to 10:30 p.m. it will be dark outside.

To get the doggy house you have to beat the game with the yellow hat. You will be able to listen to a song. (The game gets harder as you change your hats).

Before you choose a level, hold both R buttons down and then choose the stage. The icons will be replaced with Ninja Stars.
