If your wondering isn’t critical to the thought I would simplify to “the monkey who might be able to see my ears” or “can possibly see my ears”. Otherwise AbouBenAdhem has the best option, though I might also suggest “The monkey whose ability to see my ears I’m wondering about”; splitting the prepositional phrase is more strictly proper but I think it reads a little better like this.

Why do they need to “flight”? They already have the massive advantage of not being locked into Nintendo’s expensive ecosystem. It’s an entirely separate market of people who specifically want to play (new & non-emulated) Nintendo games and nothing else.
