This level is very similar to Thriller Bridge.
It is considered one of the hardest stages up to this point, but not as hard as the infamous preceding stage, Crunchy Pillar.
If not planning to use rich cat stall the peons and Master A. by using Crazed Tank Cat/ Tank Cat to max out your wallet. Once your wallet is maxed out, send out some of your midrange attackers (e.g paris or dragon) to slowly chip the Master A. After the Master A. is dead, send out all your heavy hitters you have. This should take care of the first wave of otters. After you take care of the otters, chip the Sloth. When the boss dies you will win.
Lineup: 4 meatshields, Paris Cat, Dragon Cat, and try to have the rest of your line up as high-damage dealers.
Strategy: Stall Master A. with a Tank Cat spam. Get your wallet to at least level 7, and wait until you have a lot of money. Use a powerhouse to take care of Master A. Send all your cats out before THE SLOTH comes out. If they're at least level 20 then you should take care of all the support troops, and still be able to attack THE SLOTH. You should have a lot of money so always send in your Lizard Cat, and send your Paris Cat whenever you want, but ALWAYS send in your meatshields.
Strategy 2 (4 stars)
Lineup: Catdam, Ururun, 4-5 meatshields including Jiangshi, Paris, A. Bahamut.
If you have catdam and a high level paris (mine is 40+14) then you should be able to do it. Stall in the beginning, jiangshi should be able to do this with some help every once in a while. Do this until you have around 10k, which is when you should get catdam and increase how many meatshields you're sending. Stall here until Master A. is dead, and then send everything except A. Bahamut. Ururun and a decent paris stack should be able to handle the otters and the other initial support enemies. Now wait for openings in the otters to send a. Bahamut to damage the sloth. Make sure the sloth isn't about to attack when you send a. Bahamut though.
Lineup: 3-4 meatshields (including dual walls), Artist Cat (to stall the master A at the beginning), Jamiera Cat/Mythical Titan Cat, Paris Cat/Cyborg Cat, Drama Cats.
- At the start, stall the Master A. with Artist Cat, while upgrading your worker Cat level to max. Stop spamming artist cats, however, if the Master A gets behind the base.
- Once the Master A is killed, start sending out Paris Cats and Drama Cats, as they will help greatly in defeating the stack of Celeboodles & Otta-Smack-Us.
- Once the stack of Otta-smack-us are down, keep sending out your AoE attackers (Drama & Paris) and the sloth will slowly get overwhelmed due to its slow attack rate and, eventually, you will win!
