Hybrid generator

Hi all, very new to this so apologies if this is a daft question.

Does anyone know of a blender tool or other piece of software that can take 2 models and use them to generate another model that is a hybrid of the original two? Using the original two models geometry as a guide. Imagine crossing a dog with a turtle or a giraffe with a bicycle…

I’ve seen some random shape generators out there but nothing more than just quite simple geometric shape generators.
