What was the deal with the 3 Sea Shells for cleaning ones popo? How does it work? Why aren’t we using them now?
Um, I don’t have a popo, so I dunno. 
POPO = poopie hole
Apparently, the “shells” had something to do with cleaning your bottom after using the restroom, as a replacement for toilet paper. But what exactly was deliberately never explained, as a joke.
Then why not : po-ho ?
In response to why the term is not po-ho:
The reason po-ho should not have been used in the stead of popo is for the simple reason that popo is the correct term. It just happens to be the appropriate term when the language you speak is German. It literally translates to butt.
Besides, a po-ho is an impoverished prostitute.
