To wake up the snake spirit Summer, you need to upgrade Summer’s Sanctuary by putting in an AC (called an “HVAC System”). This is done by talking to the spirits, getting the request, and gathering the needed material for the upgrade.
This guide will cover everything you need to know to complete this process, install the HVAC System, and wake Summer up.

Waking Summer Up

After completing the request “The Oneness and the Wholeness”, you’ll find Summer asleep in her cabin once you get back on the boat.
You can try waking her up, but nothing will happen.
But a couple of in-game days later, Alice will talk to you and ask why Summer has been sleeping for so long. The other spirits on the boat will also ask where Summer has been.
Alice will then recommend you to visit Albert’s Shipyard (X: 61, Y: 64) to try and figure out what’s happening.
This will trigger the “A Cold and Dreamless Slumber” request for Summer.
Once you’re at Albert’s shipyard, he’ll explain to you that since Summer is a cold-blooded animal (snake) she’ll need a temperature-controlled room. He’ll also give you an HVAC system upgrade blueprint.

This HVAC upgrade requires:
HVAC System Upgrade | |
---|---|
Requirement | Where/How to Get |
5 Copper Ingots | Made by smelting copper ore in the Foundry. Copper ore is mined from nodes found at:
You can also chance upon some copper ingots at the floating crates scattered across Furogawa region. |
5 Iron Ingots | Made by smelting iron ore in the Foundry. Iron ore is mined from nodes found at:
|
2 Glasses | Made by smelting empty bottles in the Foundry. Empty bottles can be bought for 20 Glims apiece from Francis the Wandering Merchant. You can also find empty bottles in floating crates. If you find a bottled message and open it, you will also get an empty bottle. |
250 Glims | In-game currency. Acquired from completing requests and selling items from the inventory. |
Once you have the items, you can get the HVAC system for Summer’s Sanctuary, and she will finally wake up.
This will also complete the request.
Additional Tasks

Once Summer is awake, she will start getting dragon visions again. This time, it’s the aluminum dragon, found at X: -132, Y: 134.
This is trickier than the first dragon, but should be no problem as long as you can manage platforming.
After defeating the dragon, Summer will be fully consoled.
And you’ll then need to take her to the Everdoor for a final goodbye.
Once she’s gone, you can collect her Spirit Flower inside her cabin.
