YOU SAID:

Borrowing a hat from a geyser? Make sure to first buy somebody’s archaic xylophone, then toss it over a cliff.

INTO JAPANESE

間欠泉から帽子を借りるか。 まず誰かの古風な木琴を購入するを確認し、崖の上に投げます。

BACK INTO ENGLISH

Or borrow a hat from a geyser. First to buy someone's quaint xylophone and make throws on the cliffs.
