With no luck in finding a flying island before the Zangyack forces, the Gokai Galleon crew find Sky Island Animarium. However, upon setting foot on Animarium, the Gokai Galleon crew are attacked by a Gormin platoon under Action Commander Bowser. Eventually, after the Gokaigers use the Turboranger Keys to win against Bowser's speed, the conflict attracts the attention of Gao Lion who proceeds to knock everyone off the island. The Gokaigers use the Jetman Keys to break their fall as Bowser rides a Sugmorin and manages to wound Ahim. The crew are about to get back up to Animarium to catch Gao Lion, realizing him to be the power they are looking for, when they are warned by Kakeru Shishi that they will not gain the Power Animal's power, with Captain Marvelous, Luka, and Joe refusing to take heed. Tending to Ahim's wounds in his office, Kakeru reveals himself as Gao Red with Doc pleading for Gao Lion, only to explains that only the Power Animal can make that call. Ahim and Doc proceed to defend Marvelous, Joe, and Luka by revealing that the three are looking for more than treasure before they are contacted that their crew mates are fighting Bowser and the Gormin. Kakeru watches the Gokaigers' fight and is astonished by Gokai Red, Gokai Blue, and Gokai Yellow save people in their own rough way before they, Gokai Green, and Gokai Pink use the Gaoranger Keys to defeat the Zugormin with the Hyakujuuken before finishing Bowser with the Gokai Blast. When Bauza and the Zugormin are enlarged, Gokaioh's Gokai Star Burst is disabled. However, Gao Lion's acceptance enables them to summon him from Animarium with the Gaoranger Keys as he and Gokiaoh combine into Gao Gaokaioh to take out the Zugormin before destroying Bowser. As Kakeru walks off after wishing Gao Lion good luck with his new partners, the pirates thank their new ally as they sail off.
- Exactly What I Aimed At: In episode 9, Luka throws her swords past the main monster to take out a group of mooks that are threatening civilians. Then she lampshades it "Good throw me!"
- Monster of the Week: Action Commander Bowser.
- Shout-Out: Gao Lion's introduction has it standing dramatically on a cliff.
