<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fun-size</span>' is the definition.<br/ ><span class="explanation-format__explanation">(fun-size can mean smaller than normal)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for mini that I've seen before include "Baby" , "vehicle" , "Little - car" , "Car; short dress" , "Brief" .)
