Maybe you could use a modified version of this.
*In case of multiple body parts, roll a die according to number of parts.
Example: Shooting at a giant octopus you rolled a 16 left leg hit. Roll one four-sided die (1d4) to determine which of the 4 tentacles you hit on the “left” side of the octopus. You rolled a 2 meaning you hit the “second” tentacle on the “left” side counting back from the head/body.

RANDOM DAMAGE TABLES
(Compatible with any D20 gaming system)
by Robert F. Miller, Sr.
This series of tables may be used in any Role Playing Game (RPG) based on the use of one twenty sided die (1d20). Hope this is a useful tool to Gamers and Game Masters (GM) everywhere. Please note these tables are based on Human anatomy; please adjust accordingly to creatures in your campaign. Wound Types are defined at the end of Tables. You may use these tables instead of applying damage to a character.
These tables are only to be used if a hit/strike is successful and hit the body part listed according to your GM/Gaming system.
