Episode 1 has Momo/Oh Pink in a net, but I could not get a decent shot. Instead to start it off here is her and Juri/Oh Yellow in episode 18 being tentacle wrapped because one mad scientist thought having alien robots turning him into a cyborg was a good idea.
Episode 24 has Momo getting suspended via ropes over a boiling pot by Bara Kekka, the machine beast (monsters of the week in this series) of that episode who also dresses as an old fashioned pirate.
Episode 31 has her getting roped up by Bara Fauzipper.
She was also tied up similarly in the movie by Kabochumpkin.
Her being hand gagged in episode 32 briefly.
Episode 42 has all the Ohrangers being chained up.
Eps 18, 24, and 44 and the movie have more shots to them for those that want to check them out.
