Nanami AGAIN in Episode 46, also crossed with Crowning Moment of Funny: She got left behind during the combination sequence involving Senpuujin-Tenkuujin and Gouraijin-Tenkuujin. After a little trip out, she then launches her dolphin mecha into the robot of the week, piloted by Wendinu, and then reveals shark tongues that bit the hip in place. Then Wendinu found out Nanami practically CLIMBED into the cockpit window, says and waves "Hi", punches the window out with bare hand... then draws scribbles onto Wendinu's face. Then she proceeds to re-combine with the rest and leads up finishing Wendinu and her robot while she's trying to clean up her face.
Hurricaneger is the first season to get a movie ten years later. We're going to get a V-Cinema release titled Ninpuu Sentai Hurricaneger: Ten Years After in August. And from what we know, not only will all five main rangers show up, but it seems Furabijo and Wendinu will, too, possibly bringing closure to the latter, who is currently the sole survivor of the Jakanja with the former's death in Boukenger vs Super Sentai.
