Here is a brief tutorial on how to make the giant blarrg function properly, First, the background has to be specific, I recommend the Cave/waterfall BG. Then place the sprite in lava/water (The water and lava require an animation in the header) but make sure the blarrg is placed 3 spaces below the lava/water. placing the blarrg in the middle of the water/lava is the best thing to do because sometimes the blarrg move's in the air even if its not in lava/water.|
You must have a BG3 for the blarrg to work properly as the fangs and eyes are the sprite, the body is a BG3, choose 02, BG3 objects 1 and leave the palette at 0, the color of the blarrg depends on it's Coordinate by the way,
Oh and the lava required is the castle lava, not the cave lava.
