I (both Julio, and the loser behind the keyboard) believe there is a place for pests (pestiness/pestfulness/pestuality) in the league. Getting your opponent thinking about something else is a huge advantage. When I skated with JPB, the opponents always had to know where he was on the ice. Starting a tussle after every frozen puck and whispering crude things before faceoffs made sure that the opponent slowly started playing Jean Paul's game, and not his or her own.
Julio has always been a little undersized, so the rattiness was a lot of sticks on calfs (not a cow pun). As a cow, Julio has those 4 stomachs working for him, so some sideline doctor pepper means that he can work up some nasty methane in the opponents crease (cows methane is released via burps as the cud transfers from stomach to stomach, not farts through the cornhole, like everyone who just learned about climate change likes to think). A loose "accidental" horn spike (like marchand accidentally dragging and high sticking opponents) is another good way to get your opponents producers off their game and off the ice.
