As said above, IT IS CRUCIAL to rush this stage. By using cats with anti-red abilities (Island Cat, Crazed Whale and Bath Cat) and fast cats (Crazed Giraffe Cat), you can beat the stage before the Assassin Bears appear. Do not try to kill them with the Cat Cannon; they are buffed. Well, that is, unless your charge is at an overwhelming number...
Note that when the player's Cat Cannon Power is upgraded to max level, it can kill the Assassin Bears.
An almost insultingly easy strategy is to simply fill your first rank with Crazed Cats in unevolved form (granting an initial $1000 via Cat Combo), and place Awakened Bahamut in the second rank. Begin the stage, wait for your money to reach $4500 and push the instant win button.
Strategy 2 (Realm of Carnage)
This strategy require some certain Combos, prevent any damage to the Cat Base.
- Line Up: Lion Cat, King Dragon Cat, Madam King, Koi Cat, Maiden Cat; Crazed Whale Cat, Island Cat and Awakened Bahamut.
- One Crazed Whale and Island Cat should take care of the Shy Boy just fine, then finish the stage with Awakened Bahamut.
Interestingly enough, there is actually a way to cheese this stage. (Credit to Chillhola) By good timing, you can glitch past the Shy Boy and quickly take out the base. First, use an Anti-Red cat, such as Elemental Duelist Cat to attack the Shy Boy and eventually knock it back. As SOON as it gets knocked back release Maglev Cat to glitch past the Shy Boy and take out the base.
This strategy needs a Unit Speed Up (M) or 2 (Sm) in your first slot.
Level 15+ Sexy Bathtub Cat, level 7+ Swimmer Cat, Ramen cat (or equivelent cheap, high damage cat) level 11+ Crazed Giraffe Cat, Lion Cat in your second slot.
Send out 1 or 2 Ramen cats, Sexy Bathtub cat and swimmer cat. Once the Shy Boy is almost dead, spam Crazed Giraffe and Lion Cat and hope that you beat it in time.
Torture Room is notable because it is easily the best stage in the game to farm building materials for the Ototo Corps, due to its ease and the fact that every material type except the meteorite drops from the stage. If you are short on materials, this is a very quick stage to run repeatedly and get some very quickly.
