Oh shut yer....! 5* terrific grid

Nice red herring with Booby---helps to recognize it's real category first. Funny enough, I managed to successfully solve despite having the wrong connection---best I could think of was animals at the end for gangLION and ballaRAT, but I think the word "ending" got me the points. Appreciated the leniency, but might be worth refining to require some form of "prep" in the answer! :)

thanks
