In this forth chapter, the game returns to where it all began: the main characters are the three goblins, each a unique personality with his own set of skills. Tchoup can pick items and keep them in his pockets, and he’s a detective. His friend Stucco is not as good at the deductive reasoning (to be honest, he’s not good at all!) – but he is strong enough to do lifting and climbing. The third goblin, Perlius, is the one with the magic powers and a dark sense of humor.

The games mix elements of adventure and puzzle gaming. In essence, the player must find the solution to each level, in order to progress to the next. An original aspect of the series is that the player usually controls multiple goblins as player characters, each of whom has a unique set of abilities (the number of letter i’s in the word "Goblin" of the title indicates the number of characters that the player may control). The player may only control one character at a time but, depending on the specific scene, may switch characters at will.
