This is bizarre. It's a parody of the Minecraft end credits (
https://en.wikisource.org/wiki/End_Poem), and it must be an intentional easter egg as I got the exact same text as you. It also doesn't trigger a network request so it must be built into the page somehow. Very strange thing to include. Also, how did you find this so quickly? I haven't found any other way to trigger it yet.
If you try to continue the conversation, the entire response is not included in the context.
