A Thorn Wall is a naturally occurring barrier-like plant which grows on the Pandoran surface. They are composed of many jungle vines which grow large, toxic thorns to form a dense, deadly obstacle.

In the NDS Game, thorn walls were obstacles in many locations. They occured particularly around prolemuris puzzles; touching a thorn wall would incur a penalty of five seconds.
