3D Model: Design A Soft, Adorable Plushie Backpack Based On A Roblox-style Character. The Character Has A Square White Torso, Gray Blocky Arms, Khaki Pants, Gray Shoes, And A White Helmet With Black Rectangular Details And A Spiky Black Hairstyle Sticking Out The Side. Its Face Is Partially Covered By A Dark Ninja-style Mask With Intense White Eyes. The Plush Backpack Should Be Small And Huggable, With A Chibi-style Look — Oversized Head, Small Body, And Soft Rounded Features. The Arms Should Be Lightly Stuffed And Sewn To Appear As If The Plush Is Hugging The Wearer’s Back. Use Soft, Fuzzy Materials For The Body And Head, And Shiny Fabric For The Helmet And Mask To Add Texture Variety. Include Hidden Zippers On The Back Or Head For Storage, And Plush Shoulder Straps Designed To Look Like The Character’s Legs. The Expression Should Be Slightly Mischievous But Still Friendly, Perfect For A Collectible Or Cosplay Backpack.
