whistle

So, I'm trying to do the third mini-game of the Sergeant Major Assault quest, and I'm getting my butt kicked. It's the part where you have to blow that stupid whistle at the recruits to make them speed up when they fall behind, and you have to have them all up with you at the end. Does anyone...

Okay, everywhere I look, Im told to check the second map (The map with Beryl-Footed Molberry) and go to around (G-9), and look inside those 4 rooms. In one of those rooms, a "???" will spawn every 2 hours. But the thing is...... Ive been here for 4 hours, and it hasnt popped. Wtf is goin on...

ive looked on mysterytour and somepage but seem cant find the info to find it, can anyone help?

Has anyone else had problems calling their choco? I cant seem to get mine to work! A few other people in my linkshell are having the same problem. It gets to about 20% then quits loading.
