A schematic of the published progression route, with quest givers, bait and hand-ins. This is not a coordinate map.
Lighthouse → Forest → Desert → Rocks → Volcano
This schematic shows quest order and named landmarks from the existing evidence. Marker coordinates and travel distances have not been measured.
Lighthouse
Lighthouse: finish the sailor’s opening requests, summon the Spider Crab with the Empty Beer Can, then bring back its quest remains for boat access.
Forest
Forest: collect three ground Leeches for the woman by the lake. Her Modified Leech summons the Giant Piranha; return its Skeleton for the Desert coordinates.
Desert
Desert: speak to the swimmer wearing yellow floaties. Bring an endangered creature to obtain the Pufferfish bait; the Carrot starts the fight.
Rocks
Rocks: catch and defeat a Tuna with the Professional Boss Lure, keep its body for the Albatross encounter, and return the bird’s Head for Volcano coordinates.
Volcano
Volcano: fulfil the scientist’s five-creature request, fight the first whale, then use its quest drop at the volcano for the final encounter. Return the final quest item to finish the route.
