Features & Capabilities

Shimeji Browser Extension brings those lovable little desktop mascots into your browser, so your web pages feel a lot more alive and a lot more fun.

Import Shimeji ZIP packs, pick your favorites, and watch them wander around your screen while you browse.

Heck, they'll even look at what youre doing and comment sometimes!

One of the best parts is how many different characters are out there. You can find all kinds of Shimejis made by artists, fandom creators, and the wider community, from sweet and cozy little companions to characters, matching your browser to your current comfort little guys

You can keep it simple with one little buddy following you around, or load up a whole group and let the page become pure mascot chaos.

User Reviews

I'm glad to have them, but like others said, they're very fast and erratic! I'd like it if they were calmer and more idle like the desktop ones. Will gladly use this more if that's fixed!

I'm glad I can finally use these things on Firefox, they're a lot of fun. I think they move too erratically though, it's kind of distracting. Older shimejis walked around slower and did their actions less frequently. Mine also don't sit on the screen quite right. I'd appreciate more customisation in their rate of activity, and maybe the ability to set them at the right position.
