Who or what exactly is a Heffalump? The lovable residents of the Hundred Acre Wood -- Winnie the Pooh, Rabbit, Tigger, Eeyore, Kanga and the rest of the pack -- embark on a journey of discovery in search of the elusive Heffalump. But as is always the case, this unusual road trip opens their eyes to so much more than just the creature they're seeking.
Unfortunately the movie Pooh's Heffalump Movie is not yet available on HBO Max.
