- There once was a Heep-heep from Zrak
- Who found himself in a crack
- The harder he tried
- To remove his backside
- The deeper he sank and that's that!
Behind the scenesEdit
The Heep-heep was introduced in a poem in Monsters and Aliens from George Lucas, a book published in 1993. Lucasfilm employee Leland Chee, who maintains the Holocron continuity database, has indicated that information contained in the book is non-canonical.
