Heffalumps and Woozles are supporting characters from the Disney's animated film, The Many Adventures of Winnie the Pooh. Originally featured as figments of Winnie the Pooh's imagination, the Heffalumps are anti-heroes, turned into heroes later on, who support Pooh, unlike the Heffalumps, who remain the bad guys, as they want to harm the hero and steal his property of honey.
In the villains wars context, they appear as trickster demons, and while they are seen fighting the Pink Elephants in the second Disney Villains War, in Disney Heroes vs. Villains and Heroes vs. Villains Wars, they are featured as partners-in-crime, as they are summoned by Sarousch and Professor Screweyes, respectively, as part of their grand perfomance.
