I never thought I would say this... but omg, that simple mooth was SO ANNOYING. Sadly, none of my cats was prepare for that, and I was not expecting that single enemy being there for so long, every time another one arrives.
So, the strat. Beating this stage now, and before (on my jp account) I can see 2 strategies here. One, dealing with the 3 Lutrinaes first, and then pushing the Gigahaniwan and the golem sunfish later with doron, or... Letting the boss close to your base and annihilating him with all your anti relic(like I did in the end with gacha units). Both strats works, but both have their own risks.
The reason why I chose the Lutrinae strat, was because it was less RNG. If you chose to let him close to your base, you NEED your Luza to hit him a LOT of times, and, since we DON'T have a good block wave units, there is a BIG chance that he will keep getting knockback/Freeze, and will end up just not being able to kill him fast enough, before Lutrinae rush all your units and start hitting the base. This strat can work better, if you use rich cat, since you can farm money with the pengs and, with some timing, on the mooth, using bullet. But still a lot of luck base on the effects he will inflict on Luza, crushing this strat really fast.
So, dealing with 3 Lutrinaes, easy? No. There is a lot going on when everyone is on the field. I was using Naala to help kill the first one, Luza the second one, and Naala the last one. But the thing is... you dont know that will happen there. You don't know if he is going to weak your units, knockback, freeze, if your supercat will block some waves, you just kinda need to hope, that he will not hit every attack, because he ended up missing a lot because of Lutrinae's knockback. So strat here, is, bring every good anti wave unit you have, that can be good here (Farmboy, Mushroom, Hitman, Naala, Shell) and hopes that they can manages to hit Lutrinae enough. Like I said, this thing knockback EVERYTHING every moment, so this CAN save you a bit from the waves, and that is the plan, sometimes. Naala usually are walking in front of him, so, with some luck, she will get knockback to a safer place, and can continue attacking everyone. Everytime this thing gets knockback, you want him to get close to you as fast as possible, so you can eliminate faster, you CANNOT let this thing acumulate, or else.. game over. So the strat is... spamming mushroom, farmboy, and hitman(if you have money to spare). Naala/Luza, farmboy, mushroom, bullet, shell for the lutrinaes.
Another thing EXTREMELY IMPORTANT, is HITTING YOUR DORON HITS. He is the key for this strat to work. If you don't let your doron attack close to them, or missing a hit, its almost a guaranteed defeat. AND, its important to use him when Lutrinae is not on the field, because the counter surge can hurt SO MUCH. Of course there is some times that you dont have option, and for this moments, you just need to hope that counter surge is off your units range.
If you manages to kill the 3... congrats, but... the stage isn't over. If your base is low oh health, you need to push everyone ASAP, but this is hard... because this lineup is not ready to deal with the Gigahaniwan face to face, and here, HERE is the moment when this stupid mooth becames a BIG problem. This flying thing DOESN'T DIE, it takes FOREVER, and the few units that can hit him, like Luza, have A LOT OF PROBLEMS HITTING HIM A SINGLE TIME, BECAUSE OF THE WAVES AND THE KNOCKBACK SPAM, that sometimes(almost always) happen. So, at this point, is managing your units, in a way that you can kill this mooth, so you can use your doron, and don't make him miss a hit. Again, this moment demands a little bit of luck too, because, it every Doron's surges are useless, like invoking very far away from these 2, you can have a defeat here, by the Golem Sunfish snipping your base over and over again. At this point, there isn't a big chance of the boss being weak, or low health, so, your best plan here, is knocking them back, while slowly dealing damage on them.
If you manage to knock them back futher enough from your base, or your base has a lot of HP, theeen, you can see a win on the horizon. Keep using your units against what is in front of them, and after some time, he will fall, but this takes a while.
Good Luck.
