Trading Up Walkthrough:

Area Residents:

Candy - Will give it all away.
She's willing to give and take anything. She will let you duplicate her boobs and pussy for the starter ones. She will allow any trade except for artificial parts or the Wet Pussy.

Tulip - She has your lips.
She will allow you to copy your starter legs with hers. She has your lips and will only trade them for either Thin Lips or Full Lips.

Hammer - He has your arm.
Hammer will not allow any trades until the Cat Ears, which can be found Backstage of the Show'n Tail, are put on his head. This will unlock Your Arms and his Large cock. Your Arms can only be traded for Svelte Arms or Strong Arms. His Large Cock can only be traded for a Pussy. If you end the game while he's got Svelte Arms and a Pussy this will give you Side Ending #7.

Jenny - She has your legs.
Her only tradable part is Your Legs, which she will only trade for Strong Legs or Smooth Legs. If you give her the cowbell it will give Side Ending #10.

Denise - Not pronounced Dee-Nice.
She has Sultry Eyes which she will allow you to copy and then you can trade them for any of the other eyes, but not the Anime Eyes.

Jacqueline - Likes to be on top.
She will allow you to copy her arms for the starter ones and then will swap for Broad Arms and back to Svelte Arms. She will only allow swaps for her pussy, and will accept a normal cock and the large cock.

Harriet - She has your hair.
She has Your Hair and will only allow a trade for Long Hair to replace it. If you give her the Red Horns then it will give Side Ending #9.

Aaron - Do not call him A A Ron.
He will let you copy his cock when you have the void between your legs, but he will not allow you to swap it after that point. He will let you copy his arms when you have the Emaciated Arms and will let you swap Svelte and Broad Arms with him after that.

Blake - Likes to be on the bottom.
He will let you copy his hair when you have wispy hair then you can swap Long and Short Hair with him. He will only allow swaps for a Pussy or Cock.

Ken - Likes dolls.
Ken will only allow trades with any and all of the artificial parts and Long Blonde Hair, but not the Long Blue Hair. The parts to trade will only show up when you have a part he wants.

Vanessa - Manages the Show'n Tail
She will only trade her arms between Strong Arms and Svelte Arms. She will only trade her lips between Full Lips and Puffy Lips. Why? Because that's all she wants.

Penny - The cocktail girl. Feels she's not worth much.
She will only trade her hair between Long and Short Hair. She will only trade A Flat Chest for Boobs or Huge Boobs. She also has your Cock and will only trade it for a Pussy.

Sadie - The Pirate Princess with the sunken chest.
Will only trade Your Chest for Boobs or Huge Boobs. She will let you copy her hair and then she will trade her Long Hair for Short Hair. She is the only character that will trade the Long Blue Hair with you. Note: Her picture will not change for hair changes.

Tim - Likes the show.
He will allow you to copy his eyes and lips from the starter ones. He will then allow trades for Full and Thin Lips as well as Piercing and Sultry eyes. If you have the Wet Pussy, he is the only character that will swap that for his Cock.

Jerry - Happy to help a friend.
He will only allow trades between A Flat Chest for Boobs or Huge Boobs as well as trades between his Cock and a Pussy. Once he has both Boobs (or Huge Boobs) and a Pussy, no other trades will be allowed. If you go to the Masquerade and back to the Show'n Tail, she will have moved to a back room and allow a copy of her, leave the player with a Wet Pussy.

Kyle - Here for a good time.
Will allow you to swap his Strong Legs for Smooth Legs.

Iris - Has your eyes.
You can swap Your Eyes back with either Piercing or Sultry Eyes. You can copy her lips with the starter lips and then trade them with Thin and Full lips after that. You can swap out her Pussy for a Cock or a Large Cock.

Pandora - The big girl that's been here a while.
She will only perform swaps. You can swap A Flat Chest, Boobs or the Huge Fake Boobs for her Huge Boobs. You can swap her Smooth Legs for Strong Legs.

Milt - Large and in charge.
He will allow the copy of his Cock with your starter part and then will accept trades for a Pussy. You can swap his Flat Chest with Boobs or Huge Boobs. If you give Milt both a Pussy and Boobs he will turn into Milly and then will only allow swaps between Boobs and Huge Boobs.

Savannah - Knows better.
She will only allow swaps to her parts. Swapping her Svelte Arms for Broad Arms and her Smooth Legs for Strong Legs will change her so she will not allow trading for those parts anymore. She will only swap her Huge Boobs with Boobs.

Profession Specific Privates

Taking the Boobs, Huge Boobs or Pussy directly from Candy or Savannah will mark that slot as belonging to a prostitute. This only happens as you leave the passage for another one. This means if you currently have Boobs and Candy has A Flat Chest, you would need to swap with Candy to give her Boobs, then go to Fair Street and back again in order for those Boobs to be flagged properly.

This goes for Pandora's Huge Boobs and Iris' Pussy. Trading from them will flag those parts as belonging to a Stripper.

Having the Debug Options On will show you this information in the Shack.
