Creature Vocal Forge is 120 creature voice sound effects. There are 12 monsters, and every one ships the same six states: idle, alert, attack, hurt, death and a special. Each creature comes from one synthesised throat, so its attack and its death sound like the same animal, and your state machine can map one state to one file name across the whole bestiary.

Everything is synthesised from code, so there is no sample licence behind it. Royalty free, commercial use, no attribution required. WAV and OGG, and there is a free demo to hear first.
AI disclosure: the code that makes the sounds was written with AI tools.
