As shown in the picture below, the appropriate clothes mentioned here refer to the blue cloak dedicated to the office. Players need to put on this cloak, or find a friend who wears this cloak to hold hands with them before they can enter the office from here. The TGC blue cloak here is different from the blue cloak in the rainforest, and there is no way to enter the rainforest blue cloak.

What about the blue cloak in the office?

Office blue cloak needs to be purchased in the office, and it costs 198 yuan. After entering, you can see the NPC in the blue cloak in the story. Players who go for the first time can find someone else to bring them in, or they can get stuck in the wall themselves. However, this kind of cloak is expensive, so you may need to consider whether to start. Personally, I don't need to spend money to buy it if it gets stuck in the wall.
