One morning in the Hundred Acre Wood, Roo and his friends Winnie the Pooh, Piglet, and Tigger are surprised when they wake up to hear a loud trumpeting noise.

Despite his determination, Roo is forbidden from participating in the expedition due to his young age, prompting him to start his own solo Heffalump hunt the day after.

During the tour, Roo and Lumpy play games together and form a strong friendship but not without accidentally making a mess of Pooh's house and Rabbit's garden.

They appeared in a nightmare sequence – along with their fellow scary creatures, the woozles – in 1968's Winnie the Pooh and the Blustery Day.

It also marked the final Winnie the Pooh film to be released in Fiedler's lifetime, as he died four months later from cancer.

The teaser was later attached to theatrical screenings of Home on the Range, Clifford's Really Big Movie, Shrek 2 and Shark Tale.

The next trailer for the film was released with the theatrical screenings of The Incredibles, The Polar Express and The SpongeBob SquarePants Movie.

In the United Kingdom, the film was released on July 11, 2005, and later in a trilogy DVD on November 7, 2011, along with The Tigger Movie and Winnie the Pooh.

"[9] Metacritic, which uses a weighted average, assigned the film a score of 64 out of 100, based on 23 critics, indicating "generally favorable" reviews.
