Pixel art sprite sheet showing seven frames of dark, glowing red and purple portal rifts with tendrils.

Create a vertical pixel art sprite sheet for a Minecraft-style animated texture. The image is 16 pixels wide and 112 pixels tall, consisting of 7 frames (each 16x16 pixels) stacked vertically. It is a portal to a dark dimension inspired by the Upside Down from Stranger Things. Use black, deep red, dark purple, and magenta. The top section of each frame should have a glowing rift core that flickers slightly across frames. At the bottom, add black and red tendrils that subtly shift between frames. Keep everything consistent and blocky. This is a seamless texture for a horror portal block in a voxel game. No text. No lighting. No shading. No characters. No 3D. No background. Only pixel art. Only game texture. Game-ready. See more
