Camp Uppercrust and Lake Summer Camp Merger (Season 3 Episode 13)
Cash Networth buys Lake Summer Camp from the FUNC (the Federal Camp agency) and fires Krupp from camp director. He also merges Lake Summer Camp and Camp Uppercrust, and lets the boys rebuild the camp on an unlimited budget (George Beard and Harold Hutchins, who request Cash to buy Lake Summer Camp). But to make Krupp happy, he buys Krupp a LeisureMyLand, and inflatable island that Krupp has wanted in Season 3 but did not have the money to buy it.
