About this extension
Hedgehog Mode Anywhere adds a customizable animated hedgehog companion to any website you visit.
Enable it from the browser toolbar, then choose skins, colors, and accessories to make the hedgehog your own. It can walk around the page, jump, land on page elements, respond to mouse dragging, and use optional keyboard controls.
The extension includes per-site controls, so you can keep the hedgehog enabled globally while disabling it on specific websites whenever you want. It runs locally in your browser and does not require an account.
