In LittleBigPlanet 1
The player Sackboy mans the Pod that revolves around the planet. Behind the Pod are three planets: the Little Big Planet itself, "My Moon", the level creation section, and the "Info Moon", a place where you can find your PSN friends and join/request them, your stats, and some level suggestions from Media Molecule.
The player navigates the planet as a sort of level select by using a DualShock 3 controller. The patches on the planet roughly represent the themes of the level. For example, a patch over England has levels featuring medieval themes, or patches over Asia represent feudal settings.
The Pod itself can be decorated with the stickers and decorations included with the game, but you may only place them on the inside of the Pod.
A later update to the game allowed a player to save their Pod decorations. This let's the player to easily restore their Pod when PSN friends are over, as well as the ability to have multiple Pod themes.
In LittleBigPlanet for PSP
On the PSP, Sackboy is no longer usable during the planet menu navigation. The menu options are the Little Big Planet for story and DLC, the Pod which is for character customization and news, "My Moon" for your levels, and the "Community Moon" for other user's levels.
The Pod returns along with the DualShock 3 controller for Sackboy to navigate with. Customization returns as usual, with options for decorating your own custom LittleBigPlanet, and even the theme of the room that your Pod is in.
When in the menus, the camera zooms more towards the planets, almost out of the pod itself, in order to help with navigation visibility.
