extension- show what pets you dont own in a trade

[Ittermat]

I made this mostly for me cuz I run G.I.F.T.S and my wishlist is useless with how many pets come in and out! I have it then I dont! So I made this to tell me what pets i dont own in a trade. theres a pawprint emoji next to them if I dont own them.


Once installed you have to go through all your pet folders so the extension can save what you have- after that it works on its own.

If you want to exclude folders you add the group id to the content.js file in the excluded group ids area. like this

Code: Select all

const EXCLUDED_GROUP_IDS = new Set([
  "4315481",   // gifts
  "1234567",   // trade stock
  "9876543"    // holding pen
]);

Its not perfect im sorry but like i said i made it for me. but i decided i might share it if you wanted to use it too.

After installing

Browse your keeper folders (it learns your art keys)

It will ignore excluded folder groupid=4315481

In trades → pet picker → 🐾 shows on art you currently have 0 of

Click the extension icon → Export/Import backup any time

If you want, tell me your other excluded folder URLs and I’ll bake all their groupids in too.



🐾 What the extension is for

This extension helps you spot pets you still need while you’re in a Chicken Smoothie trade, based on the art you actually keep, not your wishlist (which lies to you 😅).

If you:

gift pets a lot,

keep “holding” or “giveaway” folders,

and want at least one of each art for yourself,

this tool acts like a personal “art Pokédex” overlay.

👀 What you’ll see

In the trade pet picker, some pets will have a:

🐾 badge

That badge means:

“You currently have ZERO of this art in your keeper folders.”

No badge = you already own at least one of that art.

🧠 How it decides what you own

The extension learns automatically by watching pages you visit.

✅ It counts pets you keep

When you visit your keeper folders, it:

looks at each pet’s image

reads the art key (pic.php?k=...)

stores how many of each art you have

If you have:

2 of the same art → count = 2

trade one away → count goes to 1

trade the last one away → count = 0 → 🐾 shows again

🚫 It ignores gift/holding folders

Folders you don’t want counted (like giveaway stock) are excluded by folder ID.

Example:

accounts/viewgroup.php?groupid=4315481


That folder:

never adds pets to your “owned” list

keeps those arts marked as “still needed”

You can add more excluded folders later.

💾 Where the data is stored

Saved locally in your browser

Survives refreshes and restarts

Nothing is sent anywhere

No account access, no automation

You also get:

Export your data to a JSON file

Import it back if needed

Reset if things ever get messy

🔒 What it does not do

❌ Doesn’t click anything for you

❌ Doesn’t accept or create trades

❌ Doesn’t read private data

❌ Doesn’t interact with other users

It only:

reads what’s already on the page

adds a small visual badge

🧩 Where it works

✅ Your pet folders (learning)

✅ Trade pet picker (highlighting)

❌ Everywhere else (it stays quiet)

🐾 TL;DR

🐾 badge = you don’t currently own this art

No badge = you already have one

Counts duplicates correctly

Ignores giveaway folders

Replaces your broken wishlist with reality

THANK YOUU this is exactly the kind of thing i was thinking was missing. in an ideal world, i'd have the game tell me what i'm missing as a completionist, and dedicate my wishlist for high priority pets only.
