You won't be able to just paste the text, because it needs its own line, and I'm not sure how you would get a newline into a named register (and I think the game author wants you to practice using o and O).
- In your picture, if you stand on the
dolphins and press o, it will start a new line where you type "believed that they were
- Next, stand on the
man, last line of the text, and press o. It will create a new line where you type "same reasons.
If it doesn't work the first time, try again in some slightly different way (navigate to
man using G instead of j, or standing on a different tile before you press o, etc.) because I had trouble the first time -- I thought it should have worked, but it gave a message about not overflowing the text boundaries or something. It worked the second time -- and I don't recall exactly what I did differently.
