×For the first goblin, you merely kill them by walking forward and then against the wall when they are orthogonally adjacent to the fegundo, and then the second one you run against the wall, facing diagonally, until he crosses path with the fegundo and dies.
This is the hardest part of the room, so avoid the next two tags if you want to solve it yourself:

×For the third one, you repeat what you did for the second one. However, while you are facing the wall when the fegundo explodes, move until you are two spaces away below the fegundo, like so:
GW
F W

×Finally, for the last goblin, move two spaces NW so the goblin is 1N from the fegundo, then move SE, NE, and then S. Finally, move SW to clear the room. Just be wary of the fegundo on the way out.
