Is this an existential question, or are you just looking for a hint?

It was definitely existential - and somehow I managed to solve the screen a couple of seconds ago.

I can't really figure out why this was the solution, but I'll roll with it.

The colours seem a shade darker here. I wonder how close we are to the final screen.

It's time to find the TSW, the Supreme Weapon (or, as the French call it- de L'arme Fatale).
Anyway, holy pixelhunt batman.

For me, this scene represents the whole game, and not because of the giant goblin head, but because all the pieces of the puzzle in this scene are quintessentially Gobliiins-style, even the double pixel hunting, which by now has become easily noticeable.

I can't really figure out why this was the solution, but I'll roll with it. 

The game manual tells us that Meliagante is a very sad giant. Make him laugh and he will be more inclined to help you find what you are looking for.

Not reading the manual - rookie mistake.

I just found out the GoG release comes with a soundtrack. I can listen to the dulcet tones of GOBLIN SPIRIT and WERE BLOUNT on my way to work.

That screen truly went Gobliiin mode.

 Now we're back here!

This is a short sequence. Two actions, both uncharacteristically obvious for this game.

A little breather before the final confrontation.

The same scene but what a difference in puzzle difficulty.

And in the end we get to ride on Flipper.

   
He's going for the bowels with his infamous potions!

This scene reminds me of the confrontation at the end of King's Quest V. Goblinized.

How many Gobliiins does it take to win this game?

They called them elves again.

So, how many times you had to repeat the cycle? ;-)
