Adored by the Network: Infogrammes Europe had a strange fondness for four of the games (Putt-Putt Enters the Race, Spy Fox 2, Freddi Fish 4, and Pajama Sam 3), often given the Fan Nickname "the Infogrammes Four". Whenever they were ready to lead foreign dubs of Humongous games, these four were usually the first in line to get dubbed, like in Italy and the UK.
Keep Circulating the Tapes: Humongous generally tried to avoid this, since they kept repackaging and re-releasing a lot of the games and putting them back on the store shelves. Putt-Putt Saves the Zoo alone was repackaged so many times that it's become remarkably easy to find.
Some of the games are now available on Steam with more coming later.
There exists conceptual designs for 3D models of the Junior Adventure characters as well as a 3D background for a Freddi Fish game that never saw the light of day, meaning the games were about to head into the 3D direction before the Atari buyout.
