Transformers Animated Season 1 Episode 14 - Nature Calls Episode Title:Nature Calls.Episode Description:Prowl is frustrated by humans plowing snow and the fact that neither Bumblebee nor Sari seem to care. Optimus Prime discovers a non- sentient Cybertronian energy signal and Sari, Prowl, and Bumblebee set off to investigate. Sari attempts to teach Bumblebee the fine rustic art of camping, but he is not the least interested in roughing it. Their semi-peaceful vacation is soon disrupted when they have a run-in with parasitic Space Barnacles, that have apparently taken over the Cybertronian body of their thought-to-have-been destroyed enemy Megatron, and end up taking over Prowl and, later on, Bumblebee. Sari uses hot water to destroy the space barnacles. Her Autobot friends are rescued, but Prof. Sumdac finds Megatron's body and takes it back to his lab to rebuild it.
