 The name Humongous Entertainment was suggested by Gilbert's ex-LucasArts colleague, Tim Schafer.It became known for creating four point-and-click adventure game series intended for young children, branded collectively as "Junior Adventures", with the four series being the "Putt-Putt" series, the "Freddi Fish" series, the "Pajama Sam" series and the "Spy Fox" series.Despite all four series being developed and released in parallel, characters from one series do not formally cross over with ones in another and instead appear as cameos or Easter eggs in any of the three other series.
