Floppy Fun Pants, since we don't include honorific in page names. This page was created under the presumption that this name is an alias, but there is non in-universe evidence for this.
Talk about it here.
Mr Floppy Fun Pants was a clown whom Harry Pike hired to come to his son Darius's sixth birthday party. The young Darius was terrified by his antics. He later said it was the worst birthday party he ever had in his life. In 2050, this fear was exploited by the Bodach, who gave him a dream in which he was locked in Mariah, his antique car, with Mr Floppy Fun Pants and three robot clowns. (TV: Dream-Eaters)
