Here are some ideas for the sets. I have many ideas, but I have first 10 possible ideas from the first season.
1. A Better Mousetrap
Minifigures: Michelangelo, Dr. Baxter Stockman (lab coat), April O'Neil (lab coat)
My idea is to make the Mouser Lab of Dr. Stockman. This set will also include 3 Mousers.
2. Meet Casey Jones
Minifigures: Donatello, Raphael, Casey Jones, Dragon Face
My idea is to make the scene where Raphael drives on his Shell Cycle and Casey Jones on his Motorcycle. This set will also include the Battle Shell.
3. Raphael vs Purple Dragons
Minifigures: Raphael, Dragon Head, Purple Dragon Member 1, Purple Dragon Member 2
My idea is to make a battle pack with the Purple Dragons.
4. Nano
Minifigures: April O'Neil, Casey Jones, Harry Parker
My idea is to make the scene with the Nano robot. I want the shop of April, the ground is enough, maybe the first floor. I want also the Nano 2.0. It's the second version of the Nano robot.
5. Our New Home
Minifigures: Leonardo, Michelangelo, Master Splinter, Foot Soldier
My idea is to make the new home of the Turtles after their home before was attacked by the Mousers. With the water, bridge and poles. Maybe some details like the televisions.
6. Leonardo vs Foot Clan
Minifigures: Leonardo, Foot Soldier (2x), Foot Tech Ninja
My idea is to make a battle pack with the Foot Clan. It will include a Foot Razor Jet.
7. The Unconvincing Turtle Titan
Minifigures: Turtle Titan, Silver Sentry, Dr. Malignus
My idea is to make the headquarters of Dr. Malignus, the archenemy of Silver Sentry.
8. Notes from the Underground
Minifigures: Donatello, Michelangelo, Quarry, Stonebiter
My idea is to make the scene with the monsters in the old underground lab of the foots. I have some pictures of it but I can't place any other pictures.
9. Stockman's Surprise
Minifigures: Donatello, Leonardo, Hun, Dr. Baxter Stockman (2nd version), Foot Soldier
My idea is to make Dr. Stockman's Exo-Suit with the minifigure of him in the suit.
10. Return to New York
Minifigures: Leonardo, Raphael, Shredder, Foot Soldier (2x), Foot Elite Guard (2x)
My idea is to make the temple that stands on the roof of Hiroku Saki's Tower. The temple with some details of the garden like the bridge, water and some trees. I want also the Foot Razor Jet. This will be the most expensive set of these sets.
These are some ideas.
