S2, E3: A little cactus inspires Urmel to teach this plant to talk with the help of the Professor’s speech-drops. First he is laughed at by the Animals, only the Professor takes his idea more seriously and sends everybody out to look for a plant with a mouth. This gives the villains the chance to come to the island with Slimeyer disguised as a plant. But in the end Tiddleypom recognises who the “eating rubber-plant” is and Slimeyer has to flee.
