Floor 9 is the 9th floor of Infernal Tower.
- 1 Master A. spawns as the boss after 3.33 seconds100f.
- Infinite Those Guys spawn after 3.33 seconds100f, delay 3.33~10 seconds100f~300f.
- Infinite Wafer Cat BIGs spawn after 23.33 seconds700f, delay 66.67~73.33 seconds2,000f~2,200f.
- 6 Gummy Cats spawn after 33.33 seconds1,000f, delay 40~43.33 seconds1,200f~1,300f.
- 2 Chocolate Wall Doges spawn after 20 seconds600f, delay 80~86.67 seconds2,400f~2,600f.
This stage is somewhat odd, as the enemies use Gummy Cat to try and stop you from getting in range of hitting Master A. The Chocolate Wall Doges aren't too big of a threat, but their Mini-Waves and high HP can make them a little annoying. Thankfully unlike the original Floor 9, there are no Assassin Bears to worry about, so there's no real reason to worry about stalling. You can use the enemies to use Long Distance or Wave Attacks to snipe Master A. without much worry, and they don't push too hard.
