Hi, long time no see.
Some good years ago, like 10 or more, there was a Ben 10 advertisement/propaganda which showed the inside of the Omnitrix.
It was like a big room, and every alien was living his life, sitting on couches watching TV and stuff like that. If I remember correctly.
I don't know if it appeared on television on the whole world or just South America -where I'm from-.
If you remember it or have a link to it, please share in the comments!
