Wanted Night is the third stage in Western Street.
The enemy base will spawn a total of 3 Shy Boys, one at the start, and 2 when the base takes enough damage as a boss. Doge Dark will be spawned at a moderate rate throughout the battle. Those Guys will be peons spawned at a moderate rate also throughout the battle. Squire Rel appears as a "target distraction" to distract cats like Bahamut from attacking the Shy Boys.
A lone Shy Boy will rush your base when the level is started. Spawn Wall Cat to stall him and to build up money. When the first Doge Dark appears, spawn Dragon Cat, and bring in Macho to the stalling party. Continue spawning these cats until Shy Boy is killed.
Once he is dead, spawn in Bahamut to prepare for the 2 Shy Boys. As your units approach the base, keep on spawning Dragon, Macho, and Wall. Bring in Sexy Legs for extra support. Once you attack the base, the 2 Shy Boys will spawn. Continue spawning the cats mentioned above until both are killed. Your units will start attacking the base and you will win the battle.
