Character Customisation is a way for the player to make their Sackperson, Toggle, OddSock or Swoop unique and different by applying various costumes and other clothing.
As well as the content unlocked by playing the Story mode, various new costume pieces can be downloaded from the PlayStation Store or from inside the game.
In order to customize the player's sack person, press the button to open the Popit Menu. Most customization can be done through the Customize Character submenu but Stickers and Decorations can also be attached using the Stickers and Decorations submenu. When applying stickers, the player's sack person is split into certain areas, the same as with costumes e.g. placing a large sticker on an eye will only colour the eye and not the rest of the face. After selecting Customize Character use the left analog stick or directional buttons to highlight different costume pieces and options. Press the L1 button or the R1 button to shuffle between pages. Press the button to try an item on and press the button again to take it off.
