Ep 17. Junklantis

The Teenage Mutant Ninja Turtles (2003) season 2 episode 17, "Junklantis," follows the four mutant turtles as they explore a mysterious underwater city made entirely of junk. The episode begins with the turtles on a routine patrol when they notice something out of the ordinary in the water. As they investigate, they discover a massive junkyard of old cars, boats, and planes that seems to go on forever.

As they navigate through the maze of wreckage, the turtles stumble upon a massive temple made entirely of junk. The temple is guarded by a group of robot soldiers, which the turtles are forced to fight in order to gain entrance. Once inside, they meet a group of merpeople who explain that they are the lost city of Junklantis.

The merpeople reveal that Junklantis was once a thriving city, but over time, it has been buried beneath layers of trash and pollution. The city's inhabitants, the merpeople, have been fighting for years to keep the junk from taking over, but they are losing the battle. The turtles offer to help clear the junk out of the city, and the merpeople gladly accept their help.

As the turtles and the merpeople work together to clear the junk, they discover that there is something strange about the city. Some of the junk seems to be moving on its own, and there is an ominous feeling in the air. The turtles investigate and discover that there is a massive creature living in the city - a creature made entirely of junk.

The creature attacks the turtles, and they are forced to fight for their lives. During the battle, they discover that the creature is actually a machine created by Dr. Baxter Stockman, their old enemy. Stockman has been using the city as a dumping ground for his failed experiments, and the junk has been fusing together to create this massive, unstoppable creature.

The turtles know that they cannot defeat the creature alone, so they call on their friends and allies for help. April O'Neil, Casey Jones, and Master Splinter all come to Junklantis to help the turtles in their fight. Together, they are able to use their skills and ingenuity to defeat the machine and restore Junklantis to its former glory.

In the end, the turtles bid farewell to their new mer-friends and promise to return soon to check on the city's progress. As they leave, they reflect on the lessons they learned during their adventure. They realize that even in the face of overwhelming odds, working together and never giving up is the key to overcoming any challenge. The episode ends with the turtles back on the surface, ready to face whatever challenges come their way next.
