How to Find the Key of Serpentis

Work-In-Progress: Check back soon for new updates.

Travel to Stage 2-1 (Rush into the Ruin) in the Ukampa Temple. Directly to the right of the exit door, you’ll find a strange block with a key symbol.

Currently, it is unknown how to activate the square. It may require completing Ukampa and collecting all 30 Golden Skulls. That is unconfirmed, and we’ll update once we know more.

Once the key block is removed, you can enter a new area to the right of the exit door. The key is in the center of the temple area. Jump in and snatch it, then exit to the world map.

How to Use the Key

With the special key, next you’ll need to travel to Stage 10-7 (Jokulkyrkja) in Antarctica. There’s a strange serpent symbol on the platform ahead. Jump onto the platform and it’ll lower into a boss fight.

To defeat the boss you’ll need to throw knives at the ceiling crystals to break each section of the dragon platform you’re riding on.

Defeat the boss to unlock Antarctica for all characters, as well as unlock Jim Hawkins. With that, you’ll also get the true ending to 1001 Spikes. Goodluck!

We can rule out beating Antarctica to remove the blocked access to the key. I’ve only completed up to 7-1, but I do have all the skulls and obviously Ukampa completed. Just went back and picked up the key.

Thanks for the tip! I’ve been scouring the internet and all I’ve read are how people have stumbled into the stone. Either it opens up or it doesn’t. Ruling out one of the options is a big help.
