Cash Networth is a character in The Epic Tales of Captain Underpants. He first appears in "The Abysmal Altercation of the Abominable Altitooth".
He owns Camp Uppercrust, a camp he mentions is the best at everything (polo shirts, wearing polo shirts, there's a lot more). It is a camp specially for the rich.
Cash Networth buys Lake Summer Camp from the F.U.N.C. (Federal Camp Agen cy) and fires Krupp from camp director. He also merges Lake Summer Camp and Camp Uppercrust and lets George and Harold rebuild the camp on an unlimited budget. To make Mr. Krupp happy, Cash buys him a LeisureMyLand, an inflatable island that Krupp wanted but could not afford.
