The Rugrats take turns climbing up to the Play Palace 3000 (PP3K) and soon find that something's amiss. As they climb higher, the Palace moves further out of their reach. It is no surprise that Angelica, the self-appointed Queen of the PP3K, is behind all of this mischief. As the Rugrats defiantly refuse Queen Angelica's demands, they soon find that she has taken control of their most treasured belongings. Tommy and company now begin their adventure to reclaim their treasures.
