Armstrong the Chicken Hawk was a co-host of The Animal Show. During season 1, he mostly hung out with Ollie the Tapir; after season 1, Bunnie Bear became his cohost. The grumpy Armstrong is usually the straight man/victim in these team-ups.
Armstrong's voice is a bit duller in 1 of The Animal Show then in the seasons after that. This is probably due to the fact that Bill Barretta was not an experienced puppeteer yet.
