Villains Jungle is the fourth stage in Alcatraz, sub-chapter 17.
Bring some meatshields, and stall at first until you get 3 Bahamut Cats. This will greatly increase your chances of winning.
Also, this level might also drop a Treasure Radar!
If you are doing this stage in 2 or 3 stars, I highly recommend that you bring some health chipping/tanky cats and crazed bahamut. Lineup: Crazed/Manic Macho, Macho/Mohawk, Gato Amigo/Samba Cat, Crazed Wall (Level 20 is a requirement) Thaumaturge, Crazed UFO (Level 20 highly recommended), Crazed Dragon (Level 10-20), (Crazed M. Titan Level 20 Required), Crazed Bahamut (Level 30), and either King Dragon, or a high damage dealing uber, like Lufalan Pasalan. When you start the battle, be sure to stall until you get a max worker cat with maxed money, and make sure to stack your dual dragons (if you don't have a high damage dealing uber). Thaumaturge is for weakening the Otta Smack-Us, Duches, and R.Ost (if the R.Ost is alone) so they don't push through your front line. Crazed Dragon/King Dragon and UFO are mainly for chipping small amounts of health of the R.Ost, and killing the extremely irritating peons. Crazed M. Titan is mainly your tanky unit to stall the peons in the beginning so you can max your worker cat. Also, if you don't have Crazed Dragon, you can replace Cyborg for him. Lastly, a level 20 Crazed Wall can tank about 3-4 hits from the R.Ost (if it isn't weakened) and about 5-6 hits (if it is weakened). Hope this strategy works!
