There’s nothing to elaborate really. The joke is just a false theory that water buffalos must be opposite of a normal buffalos. So hypothetically, if buffalos were to throw water balloons, then water buffalos must throw dirt balloons. In a similar vein, if a buffalo were to enjoy taking baths in water, then water buffalos must enjoy taking dirt baths.
