On this page of the guide to Poppy Playtime you will find a walkthrough of part 4 of chapter 2. We have described how to get to Wack-A-Wuggy and what are the rules of this puzzle/minigame.
Reutrn to the hub
After completing the Musical Memory puzzle, you must return to the room that serves as the hub. From there, you will get to your next tasks that will push the story forward. To get there, you have to go through several corridors and rooms first. You'll start with the toy warehouse. The first thing you have to do is drag the hook to the dinosaur platform. You'll use your hands to drag it.
Place the hook over the dinosaur and then activate the lever. When the hook picks up the toy, move your hands over the hook to make the entire object come off the platform. Then jump on the platform, click the red button and go further.
As you walk down the hallway, you will see another platform-based puzzle. In this case, you have to drag the light beam between the two columns to push the story forward.
Next, you will go through a staircase until you reach a door blocked by a chair. Push the chair aside with your hands and step inside.
Pulling the second lever on the mechanism will open the passage to Wack-A-Wuggy. This is another puzzle, this time based on perceptiveness and reflex, not memory
You have to watch the passages carefully and use your hands to hit the enemies that will move out of the tunnels. If you miss even one, it will attack you, and you will have to start this stage all over again.
After completing the minigame, you will receive a clue and a way out. Leave the room and go to the next parts of the building. The walkthrough for the next part can be found on a separate page of the guide.
