Boggart's Breakfast

Beware the peakland spooklights, Beware the lights of blue
Make sure your nighttime wanderings are not the death of you
Don't turn aside, don't leave the track, for once you've spotted us, there's no going back
Through bog and mire, through pool and pond, sunk in swamps and depths beyond
O'er hill and crag, strange lights of blue
Wild boggarts now will dance for you...
