WILHELM SCREAM: (At around 9 mins) Clone Trooper who gets knocked over when the Zillo Beast steps on a rock, destroying it.
The episode draws heavily from the giant monster movies of the 1950s. The Zillo Beast's name and roar both reference Godzilla (1954), and the creature's appearance and depiction as an awakened prehistoric creature also reference The Beast from 20,000 Fathoms (1953).
The Dugs on Malastare are the same species as Sebulba, Anakin's opponent during the Podrace in Star Wars: Episode I - The Phantom Menace (1999).
The Aurabesh lettering on the Electro-Proton Bomb reads 'Caution Ion Detonator' and 'Code Switch Designator Position 1, Position 2, Position 3, Position 4' in red lettering on the main body and 'This is for you Dooku' in yellow on the fin.
At around 8 mins during an injured Stormtrooper scene, Mace Windu calls for troopers Trapper, Barns and Hawkeye to follow him. A play on doctors Trapper John, Major Frank Burns and Hawkeye, the three major characters of the M*A*S*H* 4077th as depicted in M*A*S*H (1972).
