Aw, c'mon, what do I get? I get one that never does anything cool but swim all day. Grrrr, I bought one expecting it to blow sand around but he never does. Ya know that means hes looking for food. Oh well, I had never seen this before except on wildlife shows. I have seen mine use his fins to move sand arounf but never his mouth. Is he using his fins or his mouth? They can shoot a pretty powerful jet out there mouth which throws sand everywhere. Oh well, mine is cool enough. I'd like to see if others have triggers that display unusual behavior.
