I noticed the Classic set has a 1x1 variant of every 2x2 tree except the 2x2 dead tree, so I made a 1x1 dead stump!

Made in Avaro's Classic XD tileset, but it should import just fine into the default Classic set. It only has two colours and a black, so even if it doesn't, I'm sure you can make it work. :)

Credits go to Avaro for Classic XD and to Nintendo for that sweet, sweet dead tree.
