This character would be either a moving character, or a preplaced one like the Ticketmen.
This character would "clean" the carnival with dirty water which might be hard to see.
BUT what the water does if following:
A) Slows down any character that walks in it by 30% (bc water and gear = rusty)
B) Makes the character fall and slip across the way. (bc water is slippery :V)
C) You will be dripping water behind you as footprints. (similar to oil trail)
