Humphey's best pals are his many animatronic bouncing Tiggers - which, incidentally, are no longer in production because their exuberant display of affection injured children. These mischievous creatures often spend time together after dinner, busting rhymes, dropping mics, and all the other things that kids do these days.
This video (seriously, it contains explicit canine-tiger content, and a parental advisory is in order!) traces Humphrey's lifelong friendship with Tigger.
