If you have Archer Cat, it may help (as awful as it is) with 3x damage to Floating. Shaman Cat is my personal favourite for Bun Bun (it's spammable and cheap, and it's only a Rare Cat so it's easy to obtain if you don't have it already.)

If you go into the Cat Guide, click 'Filter' and then 'Floating', it will display all Anti-Floating Cats. If you post them on here, it will be easier to see what is the best option for your lineup.

After 20 or so attempts at Moon 3, I managed to beat it with a massive Dragon stack (Gross can help too). Use 2-3 meatshields, and maybe use Rich Cat.
