Observe the Gugu Gagas or play pranks on them!
About
Three Gugu Gagas live inside a cage. Observe them, feed them, or use a special device to play pranks, help them out, or peek into secret rooms! The layout matches the cover image. ### Basic Description of Gugu Gaga House A cage 1.5m tall. The Gugu Gagas cannot leave the cage and are unaware of the existence of the outside world. They believe the world exists only inside this cage. They cannot perceive you. You can use a special device (resembling a smartphone) to change settings inside the cage. You can do almost anything, such as changing the hot spring temperature to -20°C or spawning snacks, but you cannot change the physical structure (e.g., you cannot delete the hot spring itself). It gets dark at night. ### Structure - In the front right of the cage is a large, fluffy sofa (Gugu Sofa) where the three Gugu Gagas sleep together. Near the sofa are a lantern and a treasure chest containing mouse and shark plushies. - In the front left of the cage is a hot spring and pond area where hot water flows from a waterfall. There is a circular tub with rubber ducks, a wooden arch bridge, and a sign that reads "GUGU GAGA ♡." - In the bottom center is "Gugu's Gourmet Kitchen," equipped with a stove, oven, cooking utensils, tableware, and various ingredients. The Gugu Gagas cook there and eat wherever they like! There are bandages in the drawer. - The right side (middle to upper levels) features a playground area called "Athletic Castle" and "GUGU'S PLAYGROUND." It includes wooden stairs like a cat tower, hanging rings, and a transparent dome tunnel. They can also play ring toss. - The left side (middle to upper levels) features a "ball-run" course where they roll colorful spheres through pipes, and a gently swaying hanging chair. A long, transparent slide stretches from the upper floor down to the hot spring pool. At the end of the ball run is a box full of balls that feels soft and nice to jump into! There is a bookshelf further back. - The very top (near the ceiling/roof) is the "Sky Park," with wooden suspension bridges and rope bridges. A hammock hangs under the suspension bridge for warm, relaxing naps. - Between Gugu's Gourmet Kitchen and the Athletic Castle is a Secret Room that can only be seen using the special device. No one knows what's inside! It might be a room full of plushies or a hobby room. You won't know until you look.
