CH-33P, nicknamed "Cheep," was a C1-series astromech droid with masculine programming that served the Galactic Republic during the Clone Wars. 
Following the Siege of Mandalore he, along with fellow astromech droids R7-A7 and RG-G1, assisted the former Jedi Padawan Ahsoka Tano after Order 66 was executed and the Republic's clone troopers turned against the Jedi. 
Alongside G-G, Cheep was subsequently destroyed by mind-controlled clones while assisting Tano and Clone Commander Rex's escape from the Tribunal.
