A way yo replace birth animation for Fertility Mode mod?

[vnhatduy2010]

Im looking for a way to change birth animation of Fertility Mode with animation from Billy's animation pack which is had a really good birth animation with animObject that actually spawn inside the belly and come out, and a few one from FillHerUp too, when deflate egg and larvar come out make the animation looks really good.

On Nexus already had an acticle tutorial how to change birth animation by using animation from BeeingFemale, its look better but still...

Anyone here now anything please share your knowledge please!
