How not to make banners

I came across this:

www.tactilesound.ru I

tried for a long time to understand the meaning of the farting hippo, and why every time he does this, the girl on the couch bounces :)

Then I read the headline - "Tactile transducers ..." - and did not believe - is this hippopotamus really tactilely transformed and makes the girl bounce? What the technique came to :)

Of course, dust from the hooves of an animal was meant, but for some reason the associations are completely different :)
