There are two endings to Revenge of the Savage Planet, and one of them is tied to the IT’S ALIVE Achievement. To unlock this achievement and unlock the final planet and the second ending, you’ll need to find all sections of the Pentaforce in Slappi’s Dens.

Stellaris Prime
There’s two different Slappi dens in Stellaris Prime, but you’ll need upgrades to reach both.
Den #1
The first one is really close to your habitat. Leave and head past the Javelin, then run straight up the hill in front of you.

Once you get to the top, you’ll see a large tree covered in butterflies with a breakable floor in front of it. Smash the floor to find your first teleporter to a Slappi Den.

Den #2
The second den on Stellaris Prime requires the late-game upgrade to remote control EKO.
Head to the Slarragon Forest teleporter and grapple across the large pink mushrooms.


Once you get over you’ll be in the same area where you captured the Hognork right at the start of the game. Run round to the right to get to a wall with a smashable wall.

Once you get into the room, you’ll need to remote pilot EKO behind the force field to disable it and unlock the next portal.

Xephyr
Den #3
This one is very simple, you’ll need the magnetic fork to smash the wall in front of it. Head to the Cactus Valley teleporter.

Run straight over the area to the rocky outcrop with the grindable rail in front of it.

Grind the rail over and use the magnetic fork to fire a crystal at the smashable wall and unveil your next Slappi den.

Zenithian Rift
Den #4
This den requires the EKO upgrade that allows you to dive underwater.
Teleport to the Bilodeau’s Floating Isles teleporter in the Peaks section of the map.

Head straight forward and dive into the pool in the centre of the room. When you’re down there, you should see a large neon sign helpfully saying this way.

Follow the signs all the way to the back of the area, and you’ll find your 4th den.

Quasadron IX
Den #5
This one is super easy – as it’s right in the middle of the map, and you’ll be able to track the objectives to unlock it through your journal, unlike the others. You’ll need all of the tool upgrades (except upgraded versions of things) to do the side objective.
Travel to the Florian’s Fuschia Festivus Teleporter and run straight ahead to find the teleporter.


Once you’ve cleared the 3 areas highlighted to fire the lasers, then you can unlock the teleporter and travel to the final Slappi Den. Once you clear it and grab the final piece of the Pentaforce, you’ll unlock the IT’S ALIVE Achievement and unlock Slappi’s Den of Fun for your reunion with Slappi!
