"They all float in here you know!..............Waka Waka."
Palpo the Clown was yet another alias of the mastermind we all know as Palpatine.
This one was used to smash fear into the hearts of hospitalized children. Palpster often went to medbays all over the galaxy dressed up as a merry clown to cheer up sick children, only to confront them with the horrors of the Dark Side. He especially liked to make them think they could see dead people.
