Time to begin adding some details to the tentacles and give the model some personality.
Before moving ahead, let's take a look at another powerful tool for editing meshes called loop cut or loop subdivide, which will be used when bending the tentacles. Loop cut adds points in the middle of an edge and all around a portion of the geometry. These points can then be transformed. Loop cut only works with edge or Vertex Select mode and will automatically switch modes when being used.
For our project, we'll be using loop cuts to bend the tentacles. Follow these steps:
