Floor 41
The scenery changes drastically, the ground is a deep purple and has static sparkles on the ground there are cracked tan tiles. The walls are made up of a light purple coral. There is a medium darkness and this is only for Floor 41.

Bosses
There are two possible bosses that the player can face that depends on whether or not the player takes the secret stairs on Floor 20.

Whiscash
If the player takes the stairs on Floor 20, but not the secret stairs, Whiscash encounters the player, and then battles the player to see how useful he is. After defeat, he leaves.

Team Razor Shell
If the player takes the Floor 20 secret stairs, the player encounters Team Razor Shell. The player walks in on them as they are trying to search for the legendary Pokémon that resides in the dungeon. They detect the player, asking how long they were eavesdropping for. Floatzel claims that there is too much at stake and tells the player they brought this upon themselves and attack. Upon defeat, and before leaving, Floatzel tells the player that their Boss will not be happy and claim that they will get revenge. All of Team Razor Shell can drop Mushrooms.

Before Fighting: After Defeating:
 * Floatzel: ...Hm.
 * Octillery: Oh, man. Why'd we even come to these ruins... I'm getting tired looking at all these ancient things... It's not like we'll find any legendary Pokémon here.
 * Floatzel: ...I think we're on the right track. The aura is getting much stronger here. I can feel it running through my fins.
 * Floatzel: ...We must be getting close to finding the legendary Pokémon who is said to lurk in these ancient ruins...
 * Seaking: Heh! Geez! I feel so hungry... Maybe we should stop for a bit and eat something?
 * Whiscash: ...Yeah man. I know, I know!!! I'm surrounded by water yet I feel so thirsty!
 * Lanturn: ...
 * Lanturn: ...Shut it, you useless burdens! I knew we shouldn't have brought you with us, I don't know why the boss even sent you two, you're just dead weight.
 * Octillery: Crikey, mate! Easy on the tone, aye? We know we are getting closer and I'm getting sleepy too. These depths are too haza-...
 * Lanturn: -Wait... I hear something!
 * Whiscash: Haha!!! It's probably just my tummy rumblin' tumblin'!
 * Floatzel: ...
 * Floatzel: ...No.
 * Floatzel: ...This is something more serious. This frequency is disturbing the ecosystem around these parts. I feel we are being watched...
 * Lanturn: ...Gaah!!
 * Lanturn: ...W-who could that be?
 * Floatzel: ...
 * Floatzel: ...
 * Floatzel: ...T-there you are!!!
 * Lanturn: ...W-who are you?!
 * Seaking: Oh geez! A stranger!
 * Floatzel: ...
 * Floatzel: ...Hey, you! How long have you been eavesdropping on us?
 * Lanturn: ...I-if just boss found out about this...
 * Lanturn: ...We would get into serious trouble!
 * Floatzel: ...No. We can't risk anything, too much is at stake!
 * Floatzel: ...Well. You brought this yourself, eavesdropper. We're going to wipe the seafloor with you!
 * Lanturn: ...We are Team Razor Shell, here we come!
 * Whiscash: Urrp! My stomach hurts more... I don't know if I can even feel hunger anymore...
 * Octillery: Yaowch! Quite the stinger, aren't 'cha mate?
 * Lanturn: Our health levels are sufficiently low, this is bad. How... How did they manage to do this to us...?!
 * Seaking: I-I think we s-should ruuuun while we still can...!
 * Floatzel: Gah, we have no choice... Boss will not be very... happy.
 * Floatzel: Hey, you! Listen, we will get our revenge, sooner or later. This isn't over, not yet. We'll be back... Don't forget....
 * Whiscash: Urrp! Wait for me!!
