Bone Yard 1F (2)

First things first, let's head outside to the yard. You'll see a plant here. Use your Poltergust to water it until it grows. There's a water pump nearby, which is important because it holds Water Ghosts. Heads up: If you don't water this plant before defeating the second boss, you'll miss out on a gold diamond later that's worth a whopping 20 million!

Check the signpost; it'll tell you a "Mister Bones" is buried here and wants some peace and quiet around his grave. Time to wake him up!

You'll find a Portrait Ghost near the dog house, shaped like a dog. Shine your flashlight on him to wake him up. He'll start "playing" with you and attack. You have two options here: either let him attack you, and Mr. Bones will eventually show up, or you can try to avoid his attacks three times.

Mr. Bones himself will start throwing bones at you. He's pretty sensitive to light, so when you're really close to him, stun him with your flashlight and then quickly vacuum him up.

Once Mr. Bones is defeated, he'll drop a bone. The dog ghost will then come over to chew on it. This is your moment to grab the ghost!
