Obviously, there are some episodes we won't be able to roleplay such as the ones where they travel into Mikey's mind or the one where the older turtles find the turtles to help them since those are like turtle episodes! So I was thinking there could be some scenarios which are mostly the girls.
1. Baby Luci!
I had this idea while listening to a song! Basically, the episode would start with Madi, Lesly, and Gabby getting mad at Luci for messing with something she shouldn't have messed with while they are on a planet. Sad, she walks away and discovers a rock which turns her into a 6 year old.
When they hear a kid crying, the team runs to see what is going on. That's when they see baby Luci on the edge of a cliff. Not knowing what else to do, Lesly starts singing softly, Madi joining in after, and then Gabby. The safely get to the now softly crying. The baby Luci runs into Leslys arms and the quickly get back to the others.
Once Luci is finally safe, the girls embark on their own journey to help Luci going through the planet. Facing some monsters as they try to keep baby Luci safe. Finally, the girls find the aging water. Madi scans it using her space Tonfa scanner. They give Luci some of the water. She ages back to normal and the girls hug and make up.
2. The Princesses of the Seasons
I made these outfits and thought it would be cute for the girls. After disappearing from the ship because of a triceraton weapon. The turtles look around for the girls because they had gotten into an argument and the turtles wanted to apologize but they can't find them. That's when Fugitoid tells them that the girls were in an alternate reality where they are princesses? After doing a bit more research and being rushed by Leo and Raph mostly. He tells them that it looks like the girls are princesses but they are trapped in their castles and the turtles has to save them.
Lesly being the princess of Winter
Gabby being the princess of Fall
Madi being the princess of Spring
And of course, Luci being the princess of Summer
Once the turtles travel to the reality. They realize why they are being trapped. The henchmen of Shredder are guarding them. Tigerclaw guarding Lesly, FishFace guarding Gabby, Bebop and Rocksteady guarding Madi and Rahzar guarding Luci.
Once the turtles get to the girls. In order to release them and go back to the ship. The turtles need to prove to the princesses that they truly love them.
