The game starts off with Angelica Pickles becoming the proud owner of a brand new "Cynthia Dream Mall Fashion Show Queen" set. However, after opening the box, she realizes that it was broken all along. However, after thinking about it, she ends up being the star.
Players play the role of Angelica, which she is exploring the shopping mall in search of stores and items to win, Starting on the 1st floor, she enters the shops to play games in order to win clothes and accessories for Angelica's fashion ensemble. Players can then enter a store to play a mini-game. By completing the mini-game, players can choose a prize. Players must collect as many clothes, wigs and accessories as they can, then enter the fashion show. In the fashion show, players play dress-up with Angelica which they create different outfits with the items they've won. The Rugrats, Fluffy, Grandpa Lou and Reptar will judge the player's outfits. Each fashion show score are worth points toward the other mall floors.
When the player wins enough points, players can use the lift to go to the next floor. Each floor features different games and new items to win. Players must stand in front of a shop and Tommy Pickles tells the players what game is inside. The items displayed in the store window show the types of prizes players can win in that game. Angelica can win shoes, clothing, hairstyles, hats, make-up, and jewelry in different stores. Angelica can go to the fashion show each time she wins an item. Every trip down the catwalk earns points toward the next floor of the mall, and players will have to visit the fashion show several times in order to earn enough points to visit the next floor. However, if the players finish the game, they have to send away "Totally Angelica" points, so they get Cynthia Dream Mall Fashion Show Queen dolls and playsets.
