This is the original series finale of Rugrats. Special: After arguing with Minka over his spotted glasses, Boris runs away. Later, after feeling bad, he decides to get Minka's glasses, only to be trapped in the attic by Angelica, Tommy & Chuckie. Each family member finds him, as well as end up being locked in the attic (it locks from the outside). While in the attic, Boris tells the story on how Passover was established. Angelica, imagining the story as it unfolds, picture herself as the Pharaoh, Tommy as Moses, and the babies as Hebrew slaves. A very interesting episode. (thetvdb.com)
