Where i can find Fofino?

I found fofino in the third room but it didnt give me the achievement

im wondering what happens

this seems a copy paste with no love that honestly I will NOT support please don't give any money to self made devs like this !!! pure cash grab IN THE BUILDING: CATS

I've been through every guide for floor 5, even those that aren't in English (my native language) and no matter what I try or how hard I look, the counter says I'm missing just one cat but none of the guides show any different cats to the ones I already have and clicking on all of them again has done nothing. I have this same issue with the Bunker level too. Anyone else have this issue?...
