All Grown Up! : Express Yourself

All Grown Up!: Express Yourself is a Game Boy Advance title derived from the television series that followed the Rugrats characters. The player assumes the role of Angelica, who manages her school's newspaper.

Progress is organized around eight missions, each representing a story for the paper. These are completed in a mode focused on locating specific characters, occasionally requiring item exchanges or the completion of mini-games to advance. Successfully finishing a mission grants an issue of the Class Paper.

Beyond the primary missions, the game includes various customization and personalization features. These allow changes to Angelica's accessories and the menu's audiovisual presentation. A PDA function lets players create personal lists, enter details about themselves and friends, or take a character matching quiz.

The mini-games encountered during story progression are also accessible as standalone activities outside the main missions.
