Reptile print at once with movable torso

This ist my newest idea. I was inspired by i fish i have seen and printed in my early days of printing. After i while i started to designed my first moving parts printed in one single step just with tinkercad. The new design was made with. Onshape for the torso. I will create some videos how i made it. I am not finished with tho whole print yet but you ca see one step bevor final state. :-)

Update:
i made 2 new versions of these 2 reptiles

Have look at the final result as a video:
