Probably gonna get downvoted for this but, at the beginning of the third map when Geoff kept saying "yes" all I could think of was Fred Fredburger from The Grim Adventures of Billy & Mandy...
"So this guy has a fetish for rocks in the water". Ray, two of these maps involved giant balls as both obstacles and tools in this HORSE match. A fetish for wet rocks doesn't sound all that weird by this point, or at least not as generic.
