In the Monkey Buisiness, you can sell pretty much anything you buy from the site with SB, which includes this month's decors. I cannot tell you how many times I've almost sold a skull decor to the Monkey this month because the decor doesn't end with the word "decor". To solve this, I suggest putting all the items into different categories whilst selling. So you'd have an Amusement category, Food catagory, Decor catagory, Background catagory, and Other catagory. All of these would simply show in the dropdown, similarly to how our different caves show while selling lions in the TC.

This could also be extended to the TC and transfers, as it'd be extremely helpful there as well.
