BestBuddy (Mochi Pet)

← Home

Desktop Mochi Pet (Chrome Web Store name: mochi pet / Best Browser Buddy) is an early interactive pet extension. Content scripts inject a physics-driven mochi you can pick up, throw, and drop so it sticks on screen. When a video plays it sits and watches with you. Popup settings cover size, color, and sound. Manifest v3 with storage, alarms, and notifications; version 0.9.8 in-repo.

Contributions

Built buddy/physics/entity content scripts for drag, throw, bounce, and stick behavior.
Video-watching companion mode and popup customization (size, color, SFX).
MV3 packaging with web-accessible images and popup menu.

Outcomes

Shipped as a playful Chrome extension (store-oriented README install flow).
Early portfolio piece that led into later pet/agent experiments (e.g. Dr. DoDo, desktop-agent).
