This would be a site to see whilst cruising down the street. The trio has giant statues of their heads driving around LA visiting tourist sites. They were flown by helicopter and driven around on a truck. They went past the Hollywood sign in the air, they driven past the Mann's Chinese Theater and possibly near the Walk of Fame as well. If your in LA you may actually spot em' !
....I can't see why they would scare you, they don't talk or move or anything.
But you bet you definitely won't be missing it if it's anywhere in your vicinity. Pretty cool to see that they're still putting things out there in the real world for advertising though. Of this magnitude especially.
