In Granny 2 you are trapped again in a scary house, but now it is even more hazardous, for now there are two villains, Granny and Grandpa. Grandma notices every noise, even the slightest. Grandpa can not hear well but attacks hard. Find a means to escape the house before time runs out.

How to Survive in Granny 2
Shut up… and know when to be loud
Granny still has “number one hearing". She can hear footsteps, things being dropped, cabinet doors opening. But in Chapter Two you can throw noise at her:
Throw things into Baby's water (children's area). The object will float down to the Sewer Deck, and if hurled expertly, the ruckus can attract Granny down there.
Drop a vase in the main room. Grandpa will come running over and you can circle and go up the steps.
If you hear Granny’s house music, the ticking of a clock or the beeping of a security camera, it signifies Grandpa is in the kitchen or security room. Knowing where they are is half the battle.
