Needle Buzzy also has a Spike in case of frontal assaults, making it impossible to kill without taking damage unless you have the Poison (for running assaults) or Electric (for electricity immunity) parts. It has a spike over the mouth, similar to Spiked Shyster.
Also, Needle Buzzy is one of the cells with the secret cell editor parts. You can see the second Electric part is slightly different from normal ones. Their tentacles are also not symmetrical (they work symmetrically in the editor, but move in opposite directions in-game, unlike normal tentacles).
