BT21 Shimeji is part of Shimeji Buddy, a free Chrome extension that adds small animated characters to every web page you open. Once you turn BT21 on, the buddy appears at the bottom of the page, walks around, climbs the sides of the window, sits on top of images and reacts when you click or drag it. It works on Google search, YouTube, Reddit, your school portal and almost any other site.

What Is BT21 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. BT21 Shimeji is our chibi buddy inspired by BT21. 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.
