Cluck

Cluck is Dr. Robotnik's pet robotic bird from Sonic the Hedgehog (SatAM). He very rarely did much other than perch on Robotnik's shoulder.

Snively didn't seem to like him much as Snively would sometimes purposely make his eyes pop out with a remote control.

Appearance
Cluck is a roboticized chicken. His body is grey and white. His eyes are black and red. His beak is orange. He also has a red rooster comb on top of his head.

Abilities
He can fly, and he also has Robotnik on his side. He's rather annoying to those around him except for Robotnik but including Snively. His beak appears to have a number of sharp teeth, which may hurt if he bites someone. Cluck cannot talk, and his clucking and crowing appears to be out of sync with his mouth movements.

Sonic Spinball
Cluck makes his only video game appearance in Sonic the Hedgehog Spinball for the Mega Drive/Genesis, referred to as Cluckbirds. Cluckbirds are a recurring badnik that flies around attempting to get in Sonic's way. Occasionally landing on Cluckbirds can provide a boost to help Sonic get to his desired destination.

Archie Comics
In Sonic the Hedgehog (miniseries) #0, Cluck appears (with dialogue) in the story "Oh No Robo, No Mo' Mobo". He has appeared only rarely in the ongoing Archie comic series including the cover of issue 1.

Trivia
