Gomu Gomu Arms

Gomu Gomu Arms is a lightweight, client-side visual mod for Minecraft 1.20.1 Forge. It gives player arms an elastic, jelly-like stretching effect during attacks and interactions.

The mod changes presentation only. It does not increase reach, alter damage, modify hitboxes, change attack cooldowns, or add server-side gameplay rules.

Features

Elastic arm animations in first person and third person
Target-aware stretching toward entities, blocks, and the crosshair
Optional held-item rendering at the end of the elastic arm
Configurable stretch, contact, and retract timing
Adjustable jelly strength, arm width, opacity, visual distance, afterimage trails, and sounds
No required content dependencies
