Town Decorations are a feature only in Dōbutsu no Mori e+. Unlike in Animal Crossing: New Leaf, the decorations are purchased from Tom Nook. The player will then be asked to choose which acre it should be placed in. After purchasing, the decoration will appear at a signpost in that acre the next day.
Town Decorations may have influenced Public Works Projects in New Leaf, as many of the decorations reappear in it.
Town decorations that are marked with an "X" are of those that have reappeared in Animal Crossing: New Leaf as Public Works Projects.
