A Shimeji is a Java-based desktop toy originating from Japan. It creates a small character that wanders around your screen. These characters interact with windows (sometimes throwing them off-screen), climb the edges of the monitor, and replicate themselves.
Because the original code is open-source, fans create "mascot packs" for their favorite characters. Ralsei, being a beloved character known for his gentle personality and fluffy appearance, is a prime candidate for this format.
