In this all-singing, all question-answering episode, Darren and John discuss baby-saving birds (photos), the sociability of varanids, whether other tetrapods could have evolved to fill our niche, whether four limbs make you a tetrapod, and, of course, the most flammable tetrapods. Also, the new Godzilla trailer, why Darren is locked in his house, and Darren's heartfelt and powerful rendition of the TetZoo Time theme tune.
