TDL nanny droids stood 1.9 meters tall and were made by AccuTronics for those who needed security for, or couldn't spend enough time with, their children. Standard equipment on the TDL was four arms covered with Synthflesh that mimicked the child's mother's scent and warmth and an internal 2L tank that could hold milk. The TDL/X1-Lioness variant had two concealed blaster cannons in their bottom arms. One such droid was combined with a YVH 1 battle droid to make Nanna, an effective nanny and bodyguard for Ben Skywalker while his parents were away. Years earlier, Anakin Solo was protected by a TDL/X1-Lioness while on Anoth. This droid was modified so that all four arms contained hidden blasters.
