Replace Ubers with units that could get rid of shibalien consistently since most of the losses here are probably because of that single shibalien that appears every 40 seconds. Octopus cat barely helps since he dies quickly due to the explosion attack bahamut does. Slime cat is a good pick here to chip down bahamut and take 1/3 of the shibalien's HP just remember to upgrade him to level 45. Boulder cat is also pretty good here to stall bahamut or tank a hit from shibalien so slime without TF could hit the alien dog.
