Converted walls

Main article: Background Walls

Converted Walls are wall types normally created by biome spread. They can also be made using Solution sprayed with the Clentaminator, and on the  Desktop version,  Console version,  Mobile version, and  Nintendo Switch version they can also be crafted or purchased (with the exception of the natural Mushroom Wall). On the  Old-gen console, 3DS, and  tModLoader versions, the Clentaminator is the only way the player can make these walls. On versions where the Clentaminator is needed these walls futhermore drop nothing when destroyed (with a hammer or explosives), which technically makes them unobtainable items on those versions.
