I've just started watching a series called Bottle Fairy, and it's simply adorable! Ugh! It's sooo cute! It started out a little confusing, to be honest, but as it goes on, it smooths out and becomes genuinely hilarious and cute!

The names of the main four characters kind of reminds me of Keroro Gunso, being Chiriri, Kururu, Sarara, and Hororo (listed respectfully in the picture)and the flying kitty is Oboro-Chan.
