Pirate

E-29 Egg Pirate is an E-Series robot from the game Sonic Adventure and its remake, Sonic Adventure DX. It appears in Knuckles the Echidna's story in the level Casinopolis. Egg Pirates can be found running in circles on the ships above the main lobby of Casinopolis. When defeated, instead of dropping an animal as most robots usually do, it drops rings for Knuckles to collect.
