Trapped in the Dreamhouse is the first episode of two specials that aired on Nickelodeon on September 1st and was later uploaded online as episode 5 of season 5. It is considerably longer than previous episodes that aired online, spanning 11 minutes.
This is the only episode where Barbie is wearing her Season Three ponytail with her main Season One dress, earrings and shoes, but wearing her ponytail up with bangs rather than her usual ponytail-up poof with swooped, combed-over bangs on the right-hand side of her forehead. She is also wearing a necklace that accessories great with her earrings in this episode.
Everyone appears in this episode except the pets, the bear, the fish, the dolphins, and the clam.
