Wally tries to be romantic with Rosa again, but she tells him she can't have a date with him because she has big plans. A prince visited her in her dreams and she decides to wait for his yacht to arrive at the sea.
However, Wally says he also has plans of moving to the city and writing an acclaimed book of poetry, and using the prize money to buy a private island. He makes a mailbox for an invitation letter to come, but it doesn't, so he makes many more mailboxes. Meanwhile Rosa has been waiting for several days for her prince to arrive, to no avail.
Dokko suggests she build a lighthouse for the prince to notice it, so she gets to work, and does it very clumsily. Wally notices her attempts and decides to help her, hoping his dream will come true as well. Dokko steps in to help too, and together they build a permanent lighthouse near the sea. However, Rosa decides to abandon her dream for now, and focus on doing other projects.
Tropes:
- Series Continuity Error: It's stated in this episode that the KikoRiki never had a lighthouse, but they did, in fact, have one some time ago.
- Shout-Out: The Prince's ship has scarlet sails.
