This Noibat model is from the AllTheMons x Mega Showdown addon to the Cobblemon Minecraft mod. All model design credit goes to that mod. I plan to design the Noivern from this pack next.

Only recommendation I have for building order is to glue the ear edges to each other before gluing to main ear piece.

You can glue this model in a sitting pose, a standing/flying pose as seen in the last image, or using toothpicks to be able to swap like I did.
