Some Digdoggers split into three when the Recorder is blown rather than shrinking. Interestingly, Link can kill just one of the three, and leave the room. Digdogger will be slain when he returns to the room. Interestingly, while the English manual suffices with calling it a sea urchin, the Japanese manual indicates it is a giant Unira - a cameo from the Nintendo classic, Clu Clu Land.
