Sisi

Sisi was a droid whose specialty was the containment and transport of dangerous materials, which it wrapped in its flexible, tentacle-like lower body. In 5 ABY, Sisi worked with the duracrete layer Jax Pavan in transporting the cloning tank containing Ysanne Isard's clone to the buried Lusankya. Sisi subsequently assisted Pavan in flooding Palpatine's secret chambers in the Imperial Palace with two-phase duracrete, helping to lay the duracrete hoses through the Palace's corridors and ensuring that it was evenly distributed throughout the volume. Isard then killed Jax Pavan by pushing him into the duracrete before adding the hardening agent.
