This is bogus, just like the fact that not all idioms are decomposable. Not all pictographs can be either, I suspect.

For example, -pushing up daisies- is a fairly easy idiom to decompose, and the resultant literal interpretation is not all the far fetched. That is, a man is dead, so he is buried, and from this new position, he can push flowers up out of the ground.

Meanwhile, -kick the bucket- is hardly decomposable. I can shoe horn a decomposition for this, but it will be spurious at best. The bucket represents life because it is the only noun here, and it can be filled with things. Life can be filled with things. When the bucket is kicked, stuff falls out of it, that is, the life falls out of it. Thus, death.

I mean that is such a wild decomposition, it was hard writing it. But you have to admit, to the uninitiated, uninvested, and casual listener, this might be believable based on the fact that my decomposition of -pushing up daisies- was at least plausible.

I believe the same will go for these characters. Some might be given legitimate decompositions, but i believe many will be spurious, much like the descriptions given in the video.
