Well, in Mexico, the most unusual names a few years ago, were some taken from the Bible, but there were also parents who had a higher education and named their children Greek or Latin names, or they gave them names from geographic places: Minerva, Platón, Sócrates, Marco Tulio, Grecia, Kenia, Georgia, América...
However, a more recent fashion has been to use foreign names, even if they sound very strange with Spanish last names for us: Chantal López, Kevin Hernández, Brandon Dylan Martínez, Brayan Sánchez, Janett Ramos, Lizbette Rodríguez, Yésica Álvarez (these last ones must have been "Brian", "Jeannette", "Lisbeth", "Jessica", but many parents don't even mind to look for the right spelling)...
I haven't seen any "Manzana" or "Plátano" yet
, but I have met girls called Lluvia (Rain), Azul (Blue), Leydi (or Leidi Di, for "Lady" or "Lady Di"), "Orema" (this one, a math teacher's daughter, who actually wanted her to be called "Teorema").
And the latest-latest fashion around here is to take a baby-name-book and pick the strangest one, or the one with an attributed significance like "the most loved", "the one who struggles till the end", "the one who will conquer", etc.
