So now you're wondering... "tree question?" heh

As those of you with a KoKP know, the cover on the LCD has a tree built in to either side and some foliage at the bottom corners. When I very first turn on my machine (but not after a reset) the trees glow red with lights behind them. During a little over a week of game play, however, I have never seen the trees light up. I don't see them light in any of the videos, but it's hard to tell. Does this ever happen? The only video I haven't seen (that is on the Yamasa site anyway) is the single big frog that belches out the 'sonic boom' looking thing, so maybe that's when the trees light?

Any thoughts?
