What Is Sonic the Hedgehog Shimeji?

A Shimeji (しめじ) is a tiny desktop mascot that lives on the edge of your screen. The idea started as a Japanese desktop-pet program and Shimeji Buddy brings it to the browser. Sonic the Hedgehog Shimeji is our games buddy inspired by Sonic the Hedgehog. It uses a hand-drawn sprite sheet with walking, climbing, falling, sitting and special animations, so it looks like a real little animation rather than a static sticker.

About Sonic the Hedgehog

Sonic the Hedgehog has been SEGA's mascot since 1991, racing through loops and collecting rings in dozens of games and two blockbuster films. Sonic Shimeji captures that speed with a fast run cycle, a spin dash and a spin jump when you click him. He also taps his foot impatiently when you leave him standing still, exactly like the classic idle animation.
