Blue's Clues (1996)

S3E20 Blue's Big Costume Party

Title: Blue's Grand Costume Celebration Plot: It’s the day of Blue's Grand Costume Celebration! All the guests are sporting a variety of creative outfits, but can we guess who is wearing what? We sharpen our observation skills to solve the mystery. Next, we skidoo into a spooky haunted house in search of the elusive Oogulah Boogulah. As the party continues, everyone joins in for a lively game of costume limbo, discovering just how low they can go while in their fabulous attire.
