Electrical Plant Monsters

Electric Guard Dogs
These chattering dog skulls power up when nearby intruders flip a programmed trigger, usually by passing near enough in their line of sight or touching certain objects. These highly magical guardians are delicate but disturbing and charged with some dangerous spells. They are meant to deal with their targets quickly. Two crystal-powered orbs rest inside the dog skull shaped casing where eyes would be. The skull twitches, chatters and laughs to encourage an enemy's retreat. (This is just a Flameskull with all the fire damage shifted to lightning damage.)

Collared Zombies
These are fairly typical zombies with the exception of the bolts on their neck, hard wired to a small burst healing chip implanted in the back of the neck, and the partly sewn-in collar with a biohazard symbol. Lightning damage dealt to zombie is translated directly to healing allowing them to be maintained by shuffling across various electric tile traps. The collar reacts to large cleansing rune spaces to insure that they can't leave the areas they are designated to and are instead immolated until nothing more than ash. This destroys the implanted chips but not the collars.

Fetal Deathdogs
These were presumably going to be completely formed Deathdogs but were accidentally dumped and escaped. The hunger the species is sometimes known for was already active and the stomach went in to overdrive producing acid to the extent it poured from the mouths like excessive salivation. Once killed these acids reacted with other artificial enzymes inside the gut cavity, causing the creature to explode in a burst of acidic splatter. (Regular Deathdogs with a burst-on-death AOE and the damage type of the bite turned to acid)

Wyrmling Tadpoles
Underformed, almost tadpole-like dragons that were being artificially grown. Many dragons can survive their egg being broken early and these seem to have inherited that hardiness though there is no way existence was terribly comfortable. These non-hostile creatures were aware and present of mind enough to be afraid and try to scare away perceived threats. They had no attacks but might have made a good healing meal for their older sibling.

The Fetal Wyrm
-Final Boss

A fully sentient, ever-hungry being with telepathy and the ability to hear telepathic thoughts no matter who they were intended to be broadcasted to. Its elemental anatomy was underformed, acid pouring from the gizzard constantly, but it was still capable of blasting a powerful breath weapon. It had no scales, exceptionally thin wing membranes, bulging eyes, and some of the features of a white dragon. The raw existence of its skin and muscles meant it was in constant pain making it very aggressive and eager to eat to try and gain sustenance for growing skin.
