Attendant demon
From Tardis Wiki, the free Doctor Who reference
Attendant demons were costumed figures in some Manussan celebrations. The attendant demons would seek out the unwary and touch them. Those touched were required to forfeit a coin. It they did not pay, the attendant demon would throw water over them.
An attendant demon touched the Fifth Doctor while he was on Manussa. Chela paid the attendant demon for him as the Doctor did not carry any coins. (DW: Snakedance)
