A Ghost Half-Shroom is a Ghost that has been forced inside of the ground by its middle break point, but with its bottom half still inside of the map. It is common for people to mistake Half-Shrooms for Ghost Shrooms despite their differences. The Ghost Half-Shroom is not a true Shroom; although its front half is identical to that of a normal Shroom, the bottom half isn't.
Comparison with Ghost ShroomEdit
Ghost Shrooms and Half-Shroomscan when viewed from certain angles can appear to be identical. The way to tell the difference is by determining if there is part of the map underneath the Shroom. If the map is a blank solid color on the underneath the surface the the Ghost is Shroomed in, then the map ends on the surface the Ghost is Shroomed in and it is a Ghost Shroom. If underneath the surface the Ghost is Shroomed in there is more of the map that you can play and walk on, then it is a Ghost Half-Shroom. The main difference lies in whether or not there are solid textures or textures you can pass through underneath the surface.
