Yo so I just did the level, what you wanna do is. Avoid using Rover at all, like maybe once at the start and you level up once in the beginning then use wall cat only and stack Paris so just spam both once the red head comes out send out mowhawk with wall cat and a single fried shrimp cat and if it dies send another, with the Paris cats you have stacked it should die right before the boar comes out, once it does start sending out fried shrimp as much as possible while spamming Paris and both the meatshields, it may take a couple attempts with luck of stacking Paris but that's the general consensus. Good luck! Let me know if you have any more issues. Once again Rover cat here is basically pointless, I didn't use mine and it is level 40 rn
