Tentacle gets out of mesh Hello Blender community,

So I'm facing a weird problem where the tentacle/arm/extremity gets outside of the mesh when the armature moves it. I've attached a couple of pictures here below. I'm trying to look for some functionality to lock the tentacle in the main body mesh. When I see other tutorials, the arms never leave the main mesh. What could be causing my model to act this way? The movement seems decently realistic as long as the armature doesn't move too far from the mesh. But once I do, the tentacle actually gets detached from the main mesh. Would appreicate any help. Thanks!!
To me, your bone chain is inverted.

You can remark that when you move the bottom bone, all come with it, but when you take the top bone it is constrained by the bottom bone :



So you can simply invert the situation (apply rotations and scale to your mesh before that). I have separated a tentacle in order you see well :


Select the armature
Go to edit mode
Select all the bones
And rotate it 180°
Adjust the Z location
Go back to object mode
Reparent the tentacle




For a more complete model, add another "top parent bone". This will allow to bring all your tentacles together and also the jelly body.
