-- now over here we're rigging up something to scatter waypoints all over the goddamn map
-- we're just tossing them out like sprinkles
-- neon lozenges, scattered upon the ground
-- colors across the leaves, sucrose stars hangin' out across the foliage
-- here comes a squirrel
-- oh look it is eating the candy! how adorable
-- we should take it home and keep it as a pet
-- now you understand waypoints.
-- Aloha.
