4 Mooths will appear at the beginning of the stage.
Very annoying level; try to kill the Mooths ASAP for money. If you can spawn Bahamut (in first or second, but not third form)*, his enormous attack power will wreck all the Mooths. JK Bun Bun might get knocked back from the blast, and the spawning of Ururun and Dark Emperor Catdam with Crazed Gross, Dragon and Macho Legs will result in quick win.
*Second opinion: Third form Bahamut does a perfect job in Sniper Jungle 3 Stars. Stall the Mooths with Crazed Cat until you get 4500, summon Bahamut to kill them and then quickly use the cash for your other main attackers like Ururun, ubers etc and upgrading your Worker level.
Third option: It is possible to cheese the strategy. Works for 1 and 2 star difficulty. Use the Crazy Hearts cat combo along with Awakened Bahamut and Swimmer Cat. Use Swimmer cat to get rid of the first mooth before sending Awakened Bahamut and more Swimmers. If done correctly, all the mooths should be dead and you can destroy the base before the J.K Bun Bun comes out with the Mawwths. Swimmer cat is optional.
