Lost media McDonalds and Cartoon Network MMO?

Does anyone remember that one app McDonald used to have that you could scan your Happy Meal to get stuff in it? I do remember it having a simple white layout! And there was also this website, I think I found out about it either from a Happy Meal box or from the app, It was a Club Penguin-esque website that you could run around as a character and there was stuff from McDonald in it, there was this specific room I remember that was completely white, only having a shop and a McDonald one from each side of the screen, it was 3d looking just like Club Penguin, I tried multiple times searching for it but I couldn't find something exact, closest thing I found was McWorld.

This room is pretty similar to my description but from my memory it was completely white, the characters were bigger and it had a McDonald in it, perhaps it's just my memory but I even wonder if this is it! Because since im 17 i'm not even sure if the site was active when I was able to play, I was probably around 4-7.

Well these aren't true lost medias since McWorld has been found and even have files for it, some crazy person just needs to actually connect it to a server, but the Happy Meal QR Code scanner certainly i've never seen anywhere, there's this Emlings one I saw that had something similar with scanning a QR Code in it but it's apparently exclusive from Australia and i'm from Brazil! I'm starting to question if it wasn't a crazy dream I had but i'm so sure it was true!!

There's also this not lost media but interresting game I remember that also has been sorta lost to time was a game about these Toonix characters?

They were on the CN website (Which is a whole rabbit hole by itself) and they had some games on it! Like a Toonix world where I remember it being pretty cool! I sadly didn't do much since I was too young but I do remember them still! And also this like other game which I'm not sure if it's the same one or a different one but you had to go through some levels as different Cartoon Network characters? Maybe i'm sounding insane here but if someone knows what i'm talking about PLEEEASE say something!

(Toonix World)

These Toonix characters are lwk Iconic can we bring them back? Used to have a toy of them back then! xD

The Cartoon Network website was so fun and I love how everything back then had a game or site about it! Kinda sad kids nowadays only really have Roblox to play around with but the times change and we can't do much but accept it! Especially after the sad end of Flash..

Feel free to drop some lost media games you also loved as a child but can't find or can only find small traces of it on the internet! Maybe we can find it!
