The Artling Gun is a tower that was the original Dartling Gun - however, after its complete construction, the creators noticed some typos in everything. Instead of darts, it fires paintbrushes which can pop through 2 bloons at a time, and pop through all layers of anything with more than 3 major colors to it (Shades and tints aren't included, but this does mean rainbows suffer terribly). It costs $950 on Medium, like its typo-free cousin tower.
