The Pirates of Dark Water - Season 3 Episode 7

Bloth comes up with a new plan after talking to a soothsaying creature who says that Ren is the only one destined to collect the treasures. He decides to become Ren by swapping bodies with him using a potion made by Morpho. He manages to catch Ren, but not without Niddler who he makes Konk swap bodies with to avoid suspicion. The potion has a drawback that any mirror will show their true identities. Ren and Niddler (now in Bloth and Konk's bodies) steal Morpho's potion and escape the Maelstrom to try to get their original bodies back. Things get a bit more complicated when Joat shows up to get revenge on Ren and Ioz for stealing The Wraith.
