Brock's eyes DO exist!

Yep, it's true. I have seen Brock's eyes. Yup yup. Where?
The episode was the one with Koga, "The Ninja-poke Showdown" or whatever. Anyway, in a scene in the end Ash is fighting Koga's Venonat with his Charmander, and Charmander is using some sort of fire attack (which suck, btw... does anybody know why?). But for some reason I don't remember (maybe it was confused or something) Charmander attacks Brock.
And then, in the beautiful moment where he is being charred by the cute little lizard and screaming in pain, you can see his eyes, wide open!
