Bartleboigle tree

The Bartleboigle tree was a tree found on Raxacoricofallapatorius. They were used by Raxacoricofallapatorians to discipline their children, using the trees to spank their backside. When the Slitheen were confronted by Sarah Jane Smith after Luke Smith escaped from them, Bloorm Vungah Bart Slitheen said to her that they would have spanked the child with a Bartleboigle tree back on Raxacoricofallapatorius.
