Screen Friend

A tiny 3D mob lives on your screen. It walks across your HUD and open menus,
minds its own business – and occasionally causes mischief. Every prank is
optional and configurable.

What it does

Steals your hunger bar and drags it around until it slides back home:

Steals your health bar:

Runs off with your hotbar:

Steals items from open inventories and throws them out into the world.
Click the thief – or the item in its hands – to rescue it in time. Theft goes
through real inventory clicks, so it works even on vanilla servers with the
mod installed client-side only:

Make it a scene

Add as many mobs as you like, each with its own model, variant and size, and
save scenes as named presets:

Any living mob in the game is available, with a searchable list and live
preview:

Resource packs

Pack models, textures and animations work on the HUD too -— models keep their
walking animations, and named pack variants (like custom enderman skins) can
be picked right in the panel. Here with Fresh Animations and its addons:

How to use

• Install with Fabric API and join a world – a friend appears on your HUD.
• Press H to open the customization panel: mobs, variants, sizes, presets.
• Mobs also idle on their own: cats, wolves and parrots sit, bipeds sit down, bats roost upside down at the top of the window.
• With Cloth Config and ModMenu installed (both optional) you get advanced settings: how often pranks happen, which ones are allowed, and manual event triggers.
• Client-side only. Nothing is installed on the server.

Works great with

Entity Model Features, Entity Texture Features and Fresh Animations: pack
models animate on the HUD just like in the world, and mobs whose pack
animates riding sit using the pack’s own animation.
