Dora Boogaranan (ドーラブーガラナン, Dōra Būgaranan) (26): A frog-like monster with an endless hunger who could swallow the Zyurangers, using either a beam projected from his horn or his long tongue after losing his horn. He could also fire energy blasts from his horn and create a force field around him to reflect energy. He was practically invulnerable, with the exception of his weak spot (the "face of truth") that was hidden beneath his neck flaps.
While Geki, Goushi, and Boi were searching for Dan and Mei, who had gone rogue due to Totpat's potion, Dora Boogaranan attacked and appeared before them. The three transformed to fight, but none of their attacks proved effective and the monster easily overwhelmed them. Dora Boogarana knocked Boi to the ground and fired an energy tongue from his horn that turned Boi into a yellow energy sphere. Dora Boogaranan swallowed the sphere and an image of TigerRanger's helmet appeared on his belly. Geki and Goushi were then forced to retreat.
Geki, Goushi, and Barza researched Dora Boogaranan and found out that its weakness was the "face of truth". Geki and Goushi returned to fight the monster and attacked its face, but still their attacks had no effect. Futilely, the Zyurangers continued to fight, but Dora Boogaranan fired its energy tongue again and swallowed Goushi, leaving Geki to fight the monster alone.
Dora Boogaranan easily overpowered Geki and was about to fire its energy tongue at him when, suddenly, Dan and Mei, having been cured of Totpat's potion, arrived on the scene and knocked Dora Boogaranan over. The two transformed to fight alongside Geki and they managed to cut off Dora Boogaranan's horn. No longer able to use its energy tongue, Dora Boogaranan retaliated by firing its actual tongue at Geki, ensnaring him. The monster pulled Geki into his mouth and swallowed him whole. As Dora Boogaranan swallowed Geki, Dan and Mei noticed the real "face of truth"; a hidden "second face" that was exposed beneath the monster's neck flaps. Deducing that Dora Boogaranan's weak point was only exposed while it was eating, Dan decided to allow the monster to swallow him, during which Mei could strike the monster's weak point. Dan threw himself at the monster and was ensnared and eaten. Before Mei could fire her Ptera Arrow, however, Totpat suddenly appeared and pushed her down. Having finished devouring Dan, Dora Boogaranan joined Totpat and fired his tongue at Mei, causing her to morph out of her PteraRanger form. Mei then retreated into a nearby forest and Dora Boogaranan and Totpat gave chase.
Unable to locate the PteraRanger, Dora Boogaranan and Totpat searched the forest while Mei devised a trap. Mei then appeared before them and pretended to give up. Satisfied with her apparent surrender, Dora Boogaranan wrapped his tongue around her, preparing to eat her. However, Mei activated a trap that fired three arrows into Dora Boogaranan's weak spot. The monster fell over and spit up the four swallowed Zyurangers. The Zyurnagers then reformed and launched a final attack on Dora Boogaranan. With that, Mei killed Boogaranan by firing a Ptera Arrow into his mouth.
