While Mrs. Twombly is desperate to get everything ready for the grand opening of Littlest Pet Street, Blythe, Roger, and the pets try desperately to get off the island.
Tropes:
- Back for the Finale: Most of the pets that previously appeared in the series return for the last time.
- Grand Finale: The second half of the two-part series finale, and the final episode of the series overall.
- Knew It All Along: It turns out Roger knew about Blythe's ability to talk to animals the whole time, because her mom had the same power.
- Last Episode, New Character: Stompy Tuffplate, a rhinoceros who lives on the island. He helps Blythe, Roger and the pets off of the island so they can get home in time for Littlest Pet Street's grand opening.
