A comprehensive Cave Story walkthrough for Grasstown. Learn how to find Santa's Key, get the Fireball weapon, and navigate treacherous areas with enemies and spikes.

Walkthrough:

  1. After the cut scene in Arthur's House, exit to Mimiga Village.
  2. Go to the top of the central save room and talk to Sue to receive your next mission and destination.
  3. Return to Arthur's House. The teleporter should now be connected to Grasstown.
  4. Select Grasstown as your destination and enter.
  5. Head right to meet Santa, who has lost his key. You need to find it for him.
  6. Continue right, encountering Critters (which take more shots to kill and can fly) and Power Critters (large blue enemies that can cause instant death if they land on you).
  7. Kill all enemies until you find Santa's Key on the ground. Be cautious due to the number of enemies.
  8. Return Santa's Key to Santa. He will ask you to follow him inside his house.
  9. In Santa's House, save and heal. Talk to Santa to receive the Fireball weapon.
  10. Note the red spikes in Santa's House; they kill in one hit.
  11. Exit Santa's House and head right in Grasstown. Gain weapon experience for the Fireball.
  12. At level 3, the Fireball becomes very effective. You can switch weapons while fireballs are active for added power.
  13. Return to the area where you found Santa's Key. There is a Life Capsule reachable with well-planned jumps from platforms with destroyable star blocks.
  14. Continue east, avoiding a spike pit, and enter another building.
  15. In Chaco's House, save and press Down in front of the fireplace. Chaco will explain that Jellyfish Juice can extinguish fires.
  16. Exit Chaco's House. New enemies, jellyfish (Kulala), will be floating around.
  17. Return to the area where Santa's Key was found. A giant jellyfish, Kulala, will be camouflaged on the ceiling. Shoot it until it dies. If a star block was left intact underneath, Kulala might get trapped, making it easier to defeat. Kulala drops Jellyfish Juice.
  18. Instead of returning to Chaco's House, go left to Santa's House.
  19. Use the Jellyfish Juice to put out the fire in the fireplace and obtain the Charcoal.
  20. Head back east, kill Kulala again to get another Jellyfish Juice.
  21. (Optional) You can return to Mimiga Village's Assembly Hall to get a new weapon, but it's not essential now.
  22. Make your way back to Chaco's House.
  23. Use the Jellyfish Juice to put out the fire, revealing a hidden door.
  24. Continue east in Grasstown. Eliminate flying bats before attempting to jump over a gap.
  25. Be careful of Mannans (white tombstone-like enemies) near spike pits. They shoot red shockwaves. Use missiles to kill them and hide in spike-less pits to avoid shockwaves.
  26. After dispatching the Mannan, drop down the edge.
  27. You will find a locked house labeled
