These are the ones I am aware of:
- The bunnygirls in the forest can have two types of scene (oral and vaginal iirc)
- The centaur girls have two scenes (giving oral or vaginal vore)
- Minotaur Boss loops through 3 animations
- The ice princess boss loops through 4(?) animations
- The witch boss loops through 3 or 4 animations
- lizardmen have a double team animation if two are nearby when you get grabbed
- Not-Krystal has two animations (one sex, one vore)
- The Werewolf boss has an animation for if he grabs you while you're naked, but also one for when you are transformed into a werewolf yourself. If you lose all your health first you don't get the werewolf on human sex scene.
- The dog guys in the town only loop one animation set, but every time it restarts you have more children
If you want to go specific, the centaur girl was posted as having anal vore, but I can see how one would see it as unbirth too. And to clarify, the minotaur boss does loop through all his animations, but the princess and witch do not. You have to escape the grab then get grabbed again to see the next one. And yeah, the princess and the witch have 3 animations each. 2 sex ones, and 1 vore one. The princess unbirths you, and the witch genderbends you, does the sex, then oral vore. Not-Krystal actually has 3 scenes as well. Another genderbend with a transformation on top of it leading to sex. Then the oral vore, and then an unbirth scene.
And I'll just throw it here again just cause, yes the dog boys are the only one with a "bad end" scene. Mega has mentioned they want to do more, but there was some technical issues with getting more in that they said they will fix when they go back through the game to touch up and fine tune things, which will be after the final boss is put in.
Oh right, the sailor in the later beach area also has two different scenes, both sex stuff.
