[Look, it's another Hoothoot - goggled, of course! Coo is the friendly one, after all. Raz isn't actually at the 'gear right now, though - he's just off-screen, in the grass of Route 7. Outskirts of Saffron, of course. He's just kind of left his 'gear there as he trains up his new Sableye and Eevee - in the background, you may even see the three battling a rather nasty Electrike. (He's got R there to help, too, of course.)
So that is why a Hoothoot is tapping at the screen, at the other Hoothoot.]
