Pac-Land

Some of the fire hydrants have a blue hard hat behind them. To get it, jump over it, turn around, and run full-speed at it. Keep running, and it’ll be pushed to the left. Eventually it will appear on your head. You can then head-butt the small ghosts (dropped from the airplanes) for 300 points each.

At the end of each level is a church. If you jump at certain places when running past it, you’ll receive bonus points.
