Donatello manages to make first contact with an alien from the newly discovered Turtle Nebula.
Tropes:
- Aliens of London: Algae speaks with a posh accent. That is after he gets his universal translator working.
- Hollywood Chameleons: Algae's species can transform into any inanimate object (or animals) as part of their fight-or-flight response.
- Psi Blast: Algae can shoot "mind energy" in the form of a bio-electric discharge.
