It's Halloween in the 100 Acre Wood, and Roo's best new friend, Lumpy, is looking forward to his first time trick-or-treating. That is, until Tigger warns them about the scary Gobloon, who'll turn them into jack-o'-lanterns if he catches them. But if Roo and Lumpy turn the tables on the Gobloon, they get to make a wish! Lumpy and Roo decide to be "brave together, brave forever" and catch the Gobloon so they can make their wishes come true.
Unfortunately the movie Pooh's Heffalump Halloween Movie is not yet available on HBO Max.
