I need help :(

Hello! Sorry for bad english yada yada yada

I am currently post-end game and the last item I acquired was the remote controller.

I am trying to free the 5 caged cats on the lower right of the map but I cannot find 2 of the 5 flute sequences...

I have literally explored the whole of the available map and even was drawing on the map on every path I traveled and I have not found the 2 remaining sequences :((

I have a theory that maybe there is no way to find these sequences and they are available if I play around with the already found sequences (like rotating de sequence etc).

Could someone give a hint, please?

Thanks in advance, I am loving this game and is probably my favorite 2024 game and favorite metroidvania game i've ever played.
