After they inquire to Clark about how a stump could be growing out of the ground, Norgu recounts a legend of an island chief who returned from the dead in the form of a vengeful tree monster called a "Tabanga".

The Tabanga monster was designed initially by Paul Blaisdell[2] (also known for his work on The She-Creature, Invasion of the Saucer Men, Not of This Earth and It!

Blaisdell's design was of a thin, spindly tree-monster with long spidery branches, which proved too narrow to fit a man inside of the costume.
