The Bathhouse Battle level in Astro Bot contains an exit that unlocks a Lost Galaxy, but it's one of the trickier locations to track down. In this case, it's wise to keep your eyes glued to the sky.

The Lost Galaxy exit is found not long after you pass the bamboo wall and use the large slide. It'll lead you to a large space with enemies, a bot to rescue, and a puzzle piece to collect.

Your first step to locate the Lost Galaxy exit is to activate the faucet and get the water running. You'll need to do this by destroying the enemies and activating the spinning wheel. Soak up the water to become Astro Bot, the sponge kaiju, and spray the nearby wall of yellow sponges.

Now, climb the sponges to the top and look for the bath to your right. The water in the bath is used to continue the level, but we're going somewhere else first. Do you see the smokestack on the roof across the way? That's our destination.

While soaked with water, walk along the top of the nearby roof while moving toward the smokestack. Jump and use your boosters to reach the island with the large torii gate. Yes, you can still jump and hover while being about 1,000 pounds of adorable sponge.

Climb the nearby cherry tree and use your sponge power's ability to shoot water and douse the smokestack. When the fire is put out, jump and use your boosters to reach the top of the stack and go down.

Congrats! You made it to the Lost Galaxy exit. Didn't I say it was a bit tricky? You may need to kill the enemy in the room, or you'll have to go through the above steps all over again. If you change your mind and want to leave, press the nearby power button to spawn a jump pad.

Taking the exit unlocks the level Furnace Fever. While I won't spoil anything, fans of FromSoftware should give the fiery stage a look as soon as they're able.
