colorful plastic tunnel 3d model

Create a low-poly 3D model of a children's plastic crawl tunnel for a playground. The tunnel must be a straight cylindrical tube (no curves), composed of simple modular segments aligned in a straight line. Each segment should have smooth rounded edges and be made of glossy colorful plastic (bright yellow, red, blue, and green). Include evenly spaced circular holes/windows on the sides of the tube. The entrance should be slightly stylized and playful, but simple (no complex character faces). Style requirements: * Low-poly, optimized for real-time game engines (Roblox-ready) * Minimal polygon count (very lightweight geometry) * Clean topology, no unnecessary subdivisions * Avoid small details that increase polycount Structure: * The tunnel should be a single clean model OR separated into simple modular segments * Keep shapes simple (mostly cylinders and basic forms) Materials: * Simple plastic material, smooth and slightly reflective * Solid colors, no complex textures
