ChefC asked:


I want to know the name of a game from the 90’s. It was a educational Kids Game for the computer. Where The main character is Green with one horn and goes around a haunted house solving games to get clues or items to put in a machine to find out who the person. The games were like you have to find adjectives out of a slot machine. Verbs. And a bunch of other Enligsh-related games.

Thanks!
