After entering it, we click on the cell to get information about grandma. During the week, we pick up a fireworks hat. Then go back to the dungeon. Click on the debris on the left to trigger some items. After obtaining a jack, we click on the birdcage, click directly to open it, and then use the magnet attached to the stick to draw out the pistol. Then leave here and go to the first floor, click on the knight's armor and add oil, you will get a fragment. Then click on the wooden mural on the table and put the fragments into it to get the second pistol fragment and a diamond ring. After that, go back to the dungeon, open the box and put the two pistols in to get a gunpowder. Return to the yard. Then use the tools to rescue the trapped animals and you will get an item tape, then look into the well and get a flashlight.
Then click on the window sill, use the diamond ring to cut the glass, and then get the firework stick. Then click on the cabinet on the right, put the fan in, and tape the wires together to get the fuse. Back in the yard, we click on the stairs on the second floor to go up to a place where fireworks are set off. We composed fireworks from the materials we obtained earlier. Give the firework and matches to the animal and get out of here. Then go to the wooden house in the yard to find a battery, and then go directly to the ledge in the corridor. Put the battery in the flashlight, then we will trigger a door opening screen, and then you will see a petrified statue. We can pick up the key from its neck and unlock grandma's pendant.
