Answer: ALBERT EINSTEIN
Problem: Valentine’s Day Town/​Arbor Day Town

This puzzle is an homage to the song “Semicolon” by The Lonely Island.

In this version, every other line clues a punctuation mark or symbol, and the preceding line clues something that rhymes with it.

Taking the letters clued by the enumeration spells RAP ABOUT ELLIPSES, which is the instruction teams must follow.

After submitting their rap, teams receive a link to an audio file which is itself a ripoff of another Lonely Island song (specifically, Spell It Out).

Using a fixed-width font, typing the rapped-out symbols makes the following image (with credit to asciiart.website):

         -''--.
         _`>   `\.-'<
      _.'     _     '._
    .'   _.='   '=._   '.
    >_   / /_\ /_\ \   _<
      / (  \o/\\o/  ) \
      >._\ .-,_)-. /_.<
          /__/ \__\
            '---'

This image, and the “Full name, yo” comment at the end of the rap confirm that the answer is ALBERT EINSTEIN.
