New Mob

Hello Everyone!

I would like to share with you my idea for a new mob that would spawn in the deep, dark ocean. The mob is called the Luminance Cephalopod, which is a type of deep-sea squid that glows in the dark with unique patterns. It is passive until provoked. If the player approaches it, its patterns will change, warning of an attack.
A new item could be obtained from this mob: the Luminance Crystal. This crystal could be extracted from a glowing organ on top of its head. The crystal could be redstoned to create a dynamic lighting block that would change its brightness depending on the strength of the redstone signal it receives. This would open up huge possibilities for Redstone-powered systems and decorations, such as a glowing floor that responds to the player's movement.
