United Kingdom is the 32nd stage of The Aku Realms.
- The enemy base here is an Aku Altar.
- 1 Henry spawns as the boss after 5 seconds150f.
- 2 Dolphinas spawn after 50 seconds1,500f, delay 46.67~50 seconds1,400f~1,500f.
- Infinite Celeboodles spawn after 10 seconds300f, delay 26.67~40 seconds800f~1,200f.
- 8 Aku Doges spawn after 10 seconds300f, delay 16.67~20 seconds500f~600f.
- 3 Condemned Pengs spawn after 30 seconds900f, delay 36.67~40 seconds1,100f~1,200f.
The main threat of this level is Henry, so any Freeze Immune (namely Li'l Eraser) and nimble (namely Awakened Bahamut, Fishman, Talented Can Can and Manic Eraser) cats are helpful. If you can sneak an attacker who can kill Dolphina and Condemned Pengs past Henry, you have already won. Celeboodles are good for money and you should kill the first one with a cat with the Extra Money ability to get prepared for what is going to come.
When attempting this stage, you should be sealed somewhere around Lv.30, so the enemies will be rather weak compared to your cats. There are many units who can get to Henry's blind spot because there is no "big" unit to help him. (Except for Dolphina, but she conveniently has a blind spot too.) If your units barely cannot reach Henry's blind spot, use Thunderbolt cannon.
This level becomes a cakewalk if you own Baby Cat. Not only is it Freeze Immune, but it also has wave attacks which help kill multiple enemies at once and snipe Dolphina.
