Can Minecraft spiders turn corners while climbing?

If I have a tall square tower, and a spider is climbing up one side of it, can it continue around to another side while still climbing? Or would it have to start climbing from the bottom again?

Similarly, if it were inside the tower and climbing on the inner wall, can it turn an inside corner and keep going? (I'm assuming yes on this one, seems easier.)

Solution 1:

No. Spiders cannot turn corners on the inside or the outside of a structure. They can move along a wall, but fall off when they try to cross a vertical corner. This video isn't a perfect demonstration but it does show in a couple of parts how the spider gets stuck trying to go round a corner. here
