Cartoon Treehouse in a Mine

A whimsical cartoon-style illustration of a treehouse built around a giant tree thriving inside a dim underground mine cavern. Warm amber lanterns hang from wooden beams, casting cozy light on rough rock walls, wooden supports, and rusted mine rails with an old minecart. Wooden platforms and balconies wrap around the tree trunk, connected by rope ladders and a arcing rope bridge. The treehouse has small doors and windows with striped curtains, a tiny chimney puffing cartoon smoke, and colorful banners. Roots weave through the platforms, creating staircases and hidden nooks. Glowing gems embedded in the walls add magical sparkle. Bold cartoon outlines, flat bright colors, and simplified shapes give a cheerful, adventurous vibe suitable for kids. The perspective is a wide, slightly elevated view that captures both the cavern ceiling and the multi-level treehouse.
