So basically my last post here was about trying to find a specific XYZ episode. Today I realize it might have been from Sun and Moon and that I was wrong when I said CN was premiering 3 year old episodes. Anyways:

Episode is about Team Rocket asking Ash to put his Pikachu into some sort of daycare, that is in the middle of the forest. At the end it's a hoax.

I'm not sure if it was from XYZ or Sun and Moon and I don't remember which people were with Ash.
