What is the strategy of Luigi Pavilion 3?

After coming out of the level of the cinema, the floor button of the elevator will be taken away by the cat demon. At this time, there will be an exploration of chasing the cat demon. Will use searchlights to illuminate the traces of the cat demon on the ground, and finally find the cat demon.

The gif below is an easy place to get stuck. The cat demon shivered in the bathtub and couldn't die. You need to vacuum the tap. After the bathtub was filled with water, the cat demon ran out.

Ghost cats have a special way of playing, and they will run away when they appear. You can check the footprints of the ghost cat with dim light, and then illuminate it with a flash after catching up, so that the ghost cat can show its true colors. At first, it will appear on the floor of the studio. After sucking off a tail, it will come to the courtyard floor on the seventh floor.

After the ghost cat shows its original shape, it will appear in a high place to observe. As long as it looks at the ghost cat, it will not come near. You need to turn your back on it, then turn around quickly, illuminate it with a flash when sticking out your nails, and then you can play like an ordinary ghost.
