Chicken Boo picture
Chicken Boo is a giant chicken who has a habit of disguising himself as a human. No matter the profession Boo has chosen, he typically excels at it.  One person in each cartoon claims he's really a giant chicken which is dismissed by the other characters in the cartoon. After Boo's disguise inevitably fails, the naysayer from earlier returns to say "I told you that guy was a chicken!" and Boo is typically shunned or even attacked by those who were praising him just minutes before.

Chicken Boo is clucked by Frank Welker.

  • Whenever the one person who knows that Chicken Boo is really a giant chicken calls him such, all of the other characters present mistakenly deny it until he clucks like a chicken, and everyone turns on Chicken Boo. However, some episodes deviated from the standard formula:
    • Katie Ka-Boo: where Mr. & Mrs. Kaboom realize he is a chicken after seeing him with their own eyes.
    • Jingle Boo: Santa Claus gave Chicken Boo a good ending to celebrate Christmas.
    • Yabba Dabba Boo: his clucking which normally gets him discovered, went unnoticed until Chicken Boo freaked out after seeing everyone eating chicken dishes.
    • Boo Happens: Several people in the episode remark that he is really a giant chicken, but only one is present at the end to say "I told you that guy was a chicken!"
    • Ralph's Wedding: Ralph says he loves chicken and everyone calms down and accepts him. Although the episode is all a dream and Ralph and his real wife eat fried chicken in bed. From a bucket that has a picture of Chicken Boo dressed up like Colonel Sanders.
    • Hooray For North Hollywood Pat 1: When Plotz turns down the Warners' movie script, Yakko believes there's only one thing to do now. Wakko believes (while Boo is walking out) it's to tell him the studio's lawyer is a giant chicken. Boo just screams and runs off before anyone else finds out.


Theme song

Chicken Boo, what's the matter with you?

You don't act like the other chickens do

You wear a disguise to look like human guys*

But you're not a man, you're a Chicken Boo

*Alternate line: 'You're jumbo-sized and you wear a disguise
