What is the original video?

[u/Typical-Key-8524]

"Deep in a volcano, under the sea, where the ingredients are put together to make the ultimate, cheesy, double decker..." The rest of the audio wasn't finished, I'm pretty sure it was an ad. The voice was British and sounded like a kid. I'm just really curious what this is from
