When you said to Gooigi, " Go save Mario from the ghost ! " but then he reveal that Mario himself is a ghost.

Another Halloween themed picture, this time Gooigi and Boo Mario.

I used different and effect for the result. I think it looks quite good. Specially the glowing effect around Boo Mario, and Gooigi "slimy" effect.
So yeah, having Luigi's Mansion 3 and Super Mario Galaxy on the same console inspiring me to draw this unluckily duo.
