Biography
After Heidi was wrongfully tossed into the mansion's basement by the wicked and treacherous governess Fraulein Rottenmeier and her butler Sebastian, she was soon surrounded by a gang of rats. Heidi attempts to befriend them, but the gang's leader, the Head Ratte, makes an appearance and reveals his evil plans in his song "Ode to a Rat", in which he sings with his gang about being rats and their desire to devour the girl.

After the rats finish their song, they corner Heidi and get into a fight with her, but soon enough, Heidi's friend Peter and his animal friends show up in a nick of time to save Heidi and engage in a battle with the rats. The Head Ratte was last seen sneaking away from the battle very nervously, and the rest of the rats were last seen tossing Sebastian's dog Schnoodle outside after they were defeated.
