Sin and Punishment is the first stage in Jail Break Tunnel.
Battleground
The stage spawns with a large group of Mooths for money. When you hit the base, a large group of R. Osts will come out.
Strategy
Cat line up: Crazed Macho Cat, Crazed Wall Cat, Eraser Cat (level 20+19 at least), Macho Legs Cat (level 20+19 at least), Crazed UFO Cat, Crazed Sexy Legs Cat, Crazed Dragon Cat, King Dragon Cat (level 20+19 at least), Valkyrie Cat and Bahamut Cat.
Item: Cat CPU.
Begin the battle, turn off "Cat CPU", increase money capacity and spawn a Bahamut Cat, when player comes to a suitable place, start spaming Crazed Cat and Crazed Wall Cat and turn on "Cat CPU", fire Cat Cannon in needed situation. You should have stacked AT LEAST 2 Bahamuts by the time you reach the base, however, 4 or more is highly recommended.
Strategy 2 by nikkiwolf22, ft. Kasa Jizo and Anubis
Cat line up: Crazed Wall Cat, Jiangshi Cat, Crazed Sexy Legs Cat, Kasa Jizo, Paris Cat, Crazed UFO Cat, Crazed Dragon Cat, King Dragon Cat, Anubis (Unblemished preferred), and Bahamut (Awakened preferred).
No items needed.
Start with some C. Walls and Jiangshis and Jizos to start killing Mooths, upgrading money in between buying other units. Wait until the R. Osts come out to buy Bahamut or Anubis (by this point you should have Lvl 8. Worker). You should have enough money to consistently keep buying every unit as it comes off cooldown, and you'll win rather quickly and without issue.

Trivia
- If enough Mooths are behind the castle and can not be hit, the ostriches can NOT spawn due to the max amount of enemies. This can be done by allowing a low-damaging stalling unit to hit the castle while the Mooths start spawning behind the castle, thus hogging enemy unit space.
