Prison Sentence is the second stage in Jail Break Tunnel.
The Doges have 1,440 HP and 128 DMG each. The B.B.Bunnies have 70,000 HP EACH, with 7,000 DMG. The Doge Darks are less deadly but very dangerous. Each one has 20,000 HP, and 8,000 DMG.
The boss, who is the Shy Boy, has 630,000 HP and does 9,000 DMG.
Begin the battle, increase money capacity level, spam Crazed Wall Cat and Wall Cat to block the Doge Darks and use (few number of) The Flying Cat to knock the dogs back. When the money is full, spawn all cat units player equipped.
Raise money first by deploying meat shields and rangers like Salon Cats. You may stack up Bahamut Cat if you want but I recommend you to stack up Hip Hop cats. The biggest threat is the Shy Boy but the Hip Hop cats can freeze it for a while.
Use wall cat, mohawk cat, crazed macho and crazed wall (or Ramen cat.) Also bring Momotaro. By the time shy boy spawns, make sure momotaro is able to freeze it forever and then your work here is done... as long as momotaro is protected! You can also use a heavy hitter (bahamut for example)
