Enter The Fly

Failing once again to destroy the Turtles, Shredder contacts Krang and insists that he needs more help. Krange acquiesces and allows Rocksteady and Bebop to enter the Portal and return to Earth. However, Krang demands a "warm body" in exchange. Shredder willingly sends the unwilling Baxter. Unbeknownst to Shredder or Krang, a common housefly also enters the Portal and arrives in Dimension X. When Baxter is thrown into the Disintegrator Chamber, the fly follows, and they are zapped by a large dose of energy. This causes them to fuse their DNA together, creating a new entity. Baxter/The Fly breaks out of the chamber, programs the Portal to return him to Earth and dives headfirst into the pulsating light.

April has received a strange bouquet of flowers. Because there is no card, she is convinced that the Turtles sent it. She arrives at the Turtles' lair and is greeted by Splinter. When he sees the plant, he grabs it out of her hands, throws it away and asks her if she has inhaled the fragrance. Moments after she says yes, she faints. When the Turtles arrive, Splinter explains that April has been sent a rare, Far Eastern Doku plant and that its fragrance causes death. He can concoct the antidote, but he needs the leaf of a Gazai plant. The Turtles hurry above ground to a local nursery, specializing in rare and exotic plants, but along the way they are attacked by Baxter/The Fly who is hell bent on revenge. They escape his attack and head back into the sewers to continue their hunt for a Gazai plant.
