IDK if you're the right person to ask, but I found a typo on the UU threatlist, under Whimsicott:
Whimsicott can also support its team with moves such as Stun Spore, Memento, Tailwind, and Sunny Day, and can boost its own Defense with Cotton Guard, making Whimsicott even more difficult to take down.
It currently says Cotton Spore.
