Rugrats: Castle Capers is a single-player platform game developed by Software Creations and published by THQ and was released only for the Game Boy Advance, based on the Rugrats cartoon series. The story revolves around the Rugrats, who must retrieve their toys from Angelica after she steals them, imagining herself to be queen of a newly constructed playground set. Gameplay is very similar to the gameplay of Rugrats: Royal Ransom and shares the same plot, released a year later.
