To unlock underwater diving in The Adventures of Elliot, push through the Water Ruins to the end — clear the enemy you run into, grab the key, open the locked door, shove the block out of the path, pick up the Magicite fragment, and open the final treasure chest, which grants the Underwater Diving ability.
Diving isn’t a button you press or something you buy — it’s the payoff for finishing a whole dungeon. The Water Ruins open up once the water level drops, and working your way to the back of them eventually hands you the ability to swim down beneath the surface. Below is the full run from the moment the water recedes to the chest that grants the dive.
What completing the Water Ruins unlocks
The reward at the end of the Water Ruins is the Underwater Diving ability. You earn it from the final treasure chest in the dungeon, after the fight, the key, the gate, and the push-block are all behind you — not from a menu, a purchase, or a keybind. If you only want the bottom line: clear the ruins end to end and the dive is yours.
One thing worth clearing up early, because the question comes up a lot: this is The Adventures of Elliot, and it has nothing to do with the “Under The Sea” swimming event from Grow a Garden 2. They’re separate games, and finishing these ruins is the only thing that unlocks diving here.
How to clear the Water Ruins and unlock diving in The Adventures of Elliot
Watch the water recede
The water level drops and opens up routes into new areas you couldn’t reach before.

Clear the enemy you run into
A fight kicks off as you press deeper, so beat it before moving on.
Grab the key
A key turns up further inside the ruins — pick it up.

Open the locked door
Use the key on the gate blocking your path and it swings open.

Shove the block out of the way
Push the block fast to clear the route ahead of you.

Pick up the Magicite fragment
A Magicite fragment is waiting near the end of the run.

Open the final treasure chest
The chest at the back of the ruins grants the Underwater Diving ability.

There’s no shortcut and no dive button — the ability only comes from the final chest, so just push all the way to the back of the Water Ruins and you’ll have it.

The Magicite fragment you pick up near the end
Right before the final chest you’ll grab a Magicite fragment. It reads as a hint that there may be a way to make new Magicite from fragments like this one — but that’s only suggested in passing, not spelled out, so treat crafting as a possibility rather than a confirmed system.
For now there’s no verified recipe, cost, or location for turning fragments into Magicite, so don’t go hunting for a crafting bench on the strength of one line. Pick the fragment up, keep it, and open the chest behind it — the dive is the guaranteed reward here.
Frequently Asked Questions
What do you actually get for finishing the Water Ruins?
You get the Underwater Diving ability, handed over by the final treasure chest at the back of the ruins. From that point you can dive beneath the surface.
Is there a key or a puzzle to get past, and how do you handle the block?
Yes to both. A key found inside the ruins opens a locked gate in your way, and just past it there’s a block sitting in the path — push it fast to shove it clear and keep going toward the chest.
Is this the same as diving or swimming in Grow a Garden 2?
No. This diving ability is from The Adventures of Elliot and is unlocked by completing the Water Ruins.
