Jungle Koopa (KBK No. 005) appears only in HTFA 6.
He appears to be a combination of Larry, Morton and Roy as he possesses Larry's hair style (albeit split into two) and eye color, part of Morton's face marking as well as mouth and teeth shape, and Roy's body shape including his shell color. He dons a grass skirt to prove that he has adapted to the jungle he lives in.
In battle, Jungle Koopa fires seeds and summons invincible Piranha Plants that disappear after a few seconds.
