<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">whale group</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for pod that I've seen before include "cocoon" , "The Borrowers father; seed case" , "Marine school" , "Seed vessel" , "Long seed case" .)
