hello i see literally no content for copper odyssey so i will be , writing down all the achievements that i got for the game which is , as of right now all but one of them

CMYK Process Gone: Beat the four bosses you need to defeat to get to the final boss.

Special Angel Tree: Beat the final boss!

Battle Monster: This one’s pretty simple, you just fight 100 battles. I think the ragtime hangout place in Cyan Kingdom is a good place to grind.

Master Print Lord Darknight: You need to get Monitor to level 99. I’ll include this later down since there’s a fight that gives loads of exp that’ll help you get the achievement.

Celeste Room invasion: You probably need all four of your friends for this one. In the castle area in Cyan Kingdom, the one close to Seymour, where if you enter you’ll be in the room where Jax is. Don’t go in the castle through the door, but go around. There will be a back door that you can go into, where two rabbit npcs offer to sell you Second Chances. The lower one, if you say yes, will transform the area so that a path is revealed to a room where two angels are guarding. Save the game, Ignore what Celeste tells you and Go inside.

JAX: You need to talk to Jax in the four locations she's in.
1. In the Cyan Kingdom, inside the castle where Seymour is in.
2. In the rightmost lower part of Black Garden, she's surrounded by rabbits.
3. In Magenta Desert, outside of Emma's old home tower thing, and next to the graveyards.
4. In the Baths, in the bottom right part of the map, right before where the school is.
5. Outside of the lithography studio in the Print studio, the path where the cake is in.
After that, go to the third floor of the print studio and talk to her there. She'll also join your party!

Speaking of Jax, she sells these things called Angel Coins, which you can trade to the artist that appears on multiple places in the game (including the area you first appear in), to get alternate costumes and stuff! (Whenever you get a costume, it doesn’t get used up, so you can still keep the angel coins.) these ones below are ones you can get using these costumes.

Fursuit: You can get the achievement by selecting the Animal outfits option from the artist.

One of the outfits that the artist has available, the Angel outfits, can make you go through walls and stuff. This is useful for getting achievements like Bomb Angel, Could be You and You Killed Villain.

Bomb Angel: Using the Angel outfits, you can go up to the top right part of Black Garden to find Rolo the Angel. Talk to him.

Could be You: SPOILERS?? Not sure if it is a spoiler but it did hit hard for me when I got this one. There is an area right before you enter the tunnels that leads to the place where you fight Emma Dimando. There’ll be a red big lookin guy behind some bars. You can’t normally access it because you can’t get past the bars, but with the Angel Outfit you can. Go interact with them.

You Killed Villain: In the second floor of the Print Studio, there is a big monster lookin guy just out of sight normally. You’ll see a glimpse of it when you go in the bathrooms as the camera goes forward with you, but you won’t be able to talk to it without the Angel Outfits. Noclipping over to it and talking to it will initiate a difficult battle. Beating it will give you the You Killed Villain achievement and probably also the Master Print Lord Darknight achievement since it , literally drops 99999999 exp

Print Collector: The wiki explains this better than I ever could, so I’ll just copy paste it here:
#01 Walk along the pathway in the Tutorial Room, starting in the center and ending to the right.

#02 In the Lithography Studio, under the entrance to the Baths, follow the entirety of the winding white pathway, starting at the left end.

#03 In the Screenprint Studio, find the rough patch of floor on the right side of the room. Starting on the leftmost tile, follow a path to the rightmost tile that steps on each tile once. Successfully doing so will spawn a print.

#04 is found by walking out the right exit of the Lithography Room. There is a yellow rabbit, and if you answer "No" to its question, it will reveal a pathway that teleports you to the Baths. There, you can take the winding path to the right of Zenny which will reveal the print. It can be picked up if you re-enter the Baths from the other side.

#05 Is found in the east of the Magenta Desert. Follow the walkway from the entrance to the eastmost tent. (the one with the guy in the front that says youll never get in this room! walk around the guy and walk off the edge, therell be an invisble path there) From here, you can walk off the right edge and take an invisible path down to another tent below. Inside that tent, there are two mats. Walk on the right mat and it will teleport you to the left mat. Walk along the left mat and the print will appear.

Completing this achievement will lead us riiiiight down to
THAT’S ME!!!!: Do what Boxer tells you to do in the print gallery in the 1st floor: get the gallery ticket and go to the Black Garden gallery, the one you normally would need a ticket to go in. There’s a boss fight there, and you have to beat it. (You can just use the Angel Outfits to go past the guy that asks you for the tickets, if you don’t feel like collecting all the prints for Boxer.

If you went about your first playthrough absolutely destroying everyone in the CMYK, you should try making friends with them! Not much changes, but its a bit more respectable to the craft.

Animal Salesman: I had the most trouble finding a way to get past Emma without killing her, but turns out you need to get her a friend! One of the houses in the top part of Magenta Desert has this weird little scrimblo guy named Gunch that runs around. If you have some turpentine on you, (which you can get by touching one of the white trees in the area) once you interact with him you can try to find out what exactly is he. Talk to Emma's assistant, the lady that lives with her husband you can ask questions to, and you'll find there's a new thing you can ask her. Do that and she'll tell you to go find someone who likes plants. That's Pharmie, the girl thats in one of the pink tents you see right when you enter Magenta Desert. Go talk to her and she'll give you an item. Give it to Gunch and he'll join your party. Now, you COULD make Emma peaceful with him, but also you could go back to Pharmie and sell him to her, which gives you the achievement. After that, try going through the cyan kingdom's entrance, and then back to the print studio.

Also, you should play through the game with only Monitor in your party, noone else. This will unlock a fair bit of achievements.
Just Another Day: Beat the CMYK with only Monitor and you'll get this achievement.

Redman: This is a weird one because you DO need to steal from Bubbles toy shop in Black Garden and get Redman'd, it just doesn't work unless you only have Monitor on your team ??

Incredible Guesser : Same with this one as well. This one is in the baths, in the wresting room (the one with Sulfie and her wrestler uncle) the copper odyssey wiki says you have to talk to her twice and input "00000000" but also it only worked for me when i was playing with just Monitor. (its okay that i needed the wiki for this one ok i already guessed 00000000 and it was wrong only because i didn't have monitor on my team)

Know-it-All..: You need to fight the Stone knight boss fight in the baths, the one a sun man teleports you to. But you can't talk to the Gift Pixie at the lower left area before beating it, because you need to do it after the fight, and then ask her to tell you something you don't know. (You do know what she tells you.) (She doesn't like that and KOs your entire party except Monitor.)

Bad end: Like the name says, you need to get the bad ending. Start a new game, and as soon as you spawn, go straight for the exit of the print studio.

I still don't know how to get the the Birthday Tooth achievement
if any of u know could u tell me i am , lost i will also add it to the guide thing
