To counter this, Dennis the Green Tree Frog forms Bush Rescue, an organization formed to counter Cass  plans. It includes Ty and Sly, his brother, Maurie as communications officer, Julius as inventor and Shazza as rescue pilot. They fight there way past disasters, both natural and Cass-Made, to learn that the cassowary is planning to use the  warm-blooded-ness  from mammals to make Uber-Reptiles. He captures the entire town and is about to subjugate them to his experiments before he is thwarted by Ty, Sly and Shazza and the cassowary is returned to jail.
