Prompt:
Cozy secret treehouse headquarters interior, rough wooden walls and floor, rope ladder entrance, small windows with forest view, warm sunlight dappled patterns, old crate table with adventure maps and glowing magic pencil, cushions, branch shelves with comics, flashlights and jars of treasures, "GEHEIM HOOFDKWARTIER" sign, string lights, high tech gear scattered: walkie-talkies, old laptop, drone parts, binoculars.
Large wall-mounted monitor on the back wall displaying detailed Bolivia research: map with pins, photos of landscapes, people and ruins, scanned old letters and notes.
Luuk (12, slim, messy brown hair, hazel eyes, light freckles, green hoodie, jeans) and Jacob (almost 13, sturdier, short red hair, bright blue eyes, glasses, gray T-shirt with open checkered shirt, jeans) sitting together focused on the table and screen, natural poses, not looking at camera.
Tiny magical creature Tikker (only 12-15 cm including tail, very small) curiously peeking from Luuk's inner jacket pocket, fluffy gray fur, large pointed ears with pink insides, big round dark eyes, black nose, whiskers, thin tail, tiny pink paws, head tilted, soft ticking sound implied.
Subtle magical sparkles around Tikker, heartwarming children's fantasy atmosphere, highly detailed, realistic style, warm natural lighting, joyful and amazed expressions
