Characters present


Dora must return a magic crown back to a mermaid named Mariana in Mermaid Kingdom and get past a mean octopus who dumps garbage all over the kingdom.


The episode starts where Dora and Boots were at the beach. They were cleaning up the beach because it is Clean Up The Beach Day. They were looking for garbage on the sand and took a juice box off a crab's head. After looking for garbage, a very special clam told Dora and Boots about Mermaid Kingdom. He told them a story about Mariana the Mermaid but she and her friends were in trouble because a mean octopus dumped garbage all over the Mermaid Kingdom and it could dissappear. He told them that Mariana discovered a magic crown put it on, made a wish and all the garbage dissappeared and the kingdom sparkled. But, one day a wave swept the crown away and Mariana needed Dora and Boots' help because the octopus was back and the garbage was making the mermaids and mermen sad and sick. Mariana tells Dora and Boots that their Mermaid Kingdom is disappearing under all the dirty garbadge and she needs their help.

Dora and Boots saw the magic crown on the sand and Dora picked it up. Map says that they had to go over Sea Shell Bridge, across Pirate Island, past the Silly Sea and then the Mermaid Kingdom.

  • This is the last episode for the original cast, namely Kathleen Herles (Dora), Harrison Chad (Boots), Sasha Toro (Backpack), Jake Burbage (Benny), and Jose Zelaya (Tico) to act before their departure due to their age, but the voices of Map, Swiper, the Fiesta Trio (all by Marc Weiner) and for at least the next season Diego (Jake T. Austin) will still be present. However, Sasha Toro will return in the 2019 movie Dora and the Lost City of Gold and voice Backpack.
  • Dora turns into a mermaid just as she puts on the mermaid crown. When she takes it off, she turns back into herself.
