Well, what is a shimeji? Well, "Shimejis are little characters or desktop buddies that play around on the sites you visit. They interact with the elements on the page. You control their behavior. Pick them up with your mouse pointer, drag them around, and drop them where you want. They can walk, crawl, climb, and jump all over the place. To have a little bit more fun you can also let them steal elements from the page. They interact with all your favorite sites. There are many shimeji characters to choose from. Each character has its own special behavior." - Chrome extension.
I really enjoy shimejis. I think they are fun and cool! Isnt it nice having a little buddy with you on most websites you visit? My shimeji is kenny from south park. Hes adorbs! :D
