Bunnie Bear replaced Ollie the Tapir after the first season. This lovable but clumsy bear teamed up with grumpy Armstrong the Chicken Hawk for segments like "That's Amazing!", "Animal Awards" and "Habitat Time".
Similar to Ollie, Bunnie helped bring in guest animals, who needed assistance (namely the insect guests).
The puppet has been used as various characters on Sesame Street with more generic, Muppet-like eyes.
