Remember those Sonic-themed LCD Games from Mcdonalds? Although I'm not from the UK, I remember seeing a commercial on YouTube a long time ago for them. and I know it very well. It was from the UK. a mix between CGI and live action.
It began with 2 kids jumping into a Happy Meal box and joining a soccer game. Sonic appears in it and helps them by rolling into the ball and hitting it in the net. They do a victory dance, and the camera brings us back to the real world where the kids eat at Mcdonalds. with the announcer saying "Get right into the action with Sonic games and the tastiest food at Mcdonalds! Sega is the next generation!" Sonic appears at the end and says something, but the upload I remember abruptly cuts it off. another thing I can note is that the upload was a camera recording of a YouTube video. which obviously means that there was a direct capture of the commercial once available.
There was also an alternate version from the US involving Soccer, that had Sonic and Knuckles. but I don't remember much about it aside from the animation looking like the CG cutscenes from Sonic Heroes.
I've searched for a long time, and I can't find them. I have no idea what happened! If anybody else knows where it could be found, that would be great.
