Krang decides to use a Hydrofluxer device to threaten to flood Venice, holding it for ransom. The Turtles, in Venice, run into Shredder as he's portaled into a Venetian sewer.

The Turtles are in Lisbon, Portugal, enjoying the sights. Krang sends Shredder and the mutants there to set up a special lens that will focus the sun's rays to create a devastating heat ray. The Turtles rescue April and Irma from Shredder, Vernon gets mixed up in a bull fight, and finally destroy the lens just as it's about to wreck the city.
