Build a detailed Plus-Plus Sonic the Hedgehog with these free 3D step-by-step instructions and interactive build guide.

This 29-block Sega character model captures Sonic's full hedgehog form — blue quills, white gloves, red shoes, and a confident standing pose in a taller 3D build than the compact Sonic figure elsewhere on the site. Gaming fans searching for "sonic the hedgehog plus plus instructions" get a display-ready hedgehog they can rotate and inspect from every angle.

Rated medium difficulty with about 5 minutes of build time. The interactive guide stacks the legs and red shoes first, then the blue body, quill row, and head where Sonic's iconic silhouette emerges block by block.

Start Building in the 3D viewer or download the PDF for offline use. Sort blues, reds, whites, and skin tones before beginning — the quill spikes and shoe color blocks define the character instantly.

Perfect for gaming desks, Sonic birthday party favors, or pairing with the 2D Sonic mosaic for a complete hedgehog collection. Press each quill block firmly for a sharp, dynamic final look.
