Looking for a scene

Watched the series with my Dad, he insists there’s a scene where a thinking machine crash lands on Arakkis and immediately gets eaten by a worm. I don’t recall any scene like this, but he insists he isn’t making anything up. We’ve already rewatched the first episode looking for it, where he claimed to of remembered seeing it, and I’m sure if it wasn’t nearly midnight he would have us rewatch the entire series.

Is this a scene that actually exists? If so, what episode/timestamp is it? We’ve had a pretty heated argument already, the quicker a response the better.
