All Grown Up! : Express Yourself

All Grown Up!: Express Yourself is a Game Boy Advance game based on Nickelodeon's All Grown Up! animated series. Developed by Altron and published by THQ, it was released in North America in October 2004. The game follows Angelica Pickles as she takes on an assignment for the school newspaper.

Angelica is the only directly controlled character in the story sections, while the rest of the familiar group supplies conversations and activities. Her reporting work is divided into eight missions, each built around pursuing a new school-related story rather than a single continuous platforming adventure.

During Story Chase play, Angelica moves through 2D locations looking for the character who can advance the current lead. Progress can also require locating specific items and delivering them to the appropriate person, then completing a minigame when the assignment calls for it.

The minigames are presented as themed activities tied to the show's characters and teen-school setting. Examples promoted for the game include helping Angelica with the newspaper, singing with Susie, assembling outfits with Lil, sharing information with friends, and taking a vote on a current topic. Seven different minigames and bonus accessories can be unlocked as players progress.

Completing activities adds collectible clothes, accessories, wallpaper, and music. These rewards can be used to personalize the main menu, making the collection system part of the game's progression between newspaper missions.

Its PDS electronic organizer works separately from the mission play. It keeps a To Do list, records information about friends, and lets the player plan a weekly schedule or store personal details. Using a Game Boy Advance Game Link Cable, players can trade accessories and selected organizer information with friends; private information can be blocked from sharing.
