A mashup of the old and new logos, I guess. Font(s) used: GG - Nick Display (slightly thicker/bolder to fit the rest of the letters)
Credit to Viacom for the Noggin logos, and for the colors. Credit to LyricOfficial (formerly Westralinc) for the Nick Display font (used for the two G's). EDIT #1: Thanks for the love and favorite, @elinery! EDIT #2: Thanks for the love and favorite, @bethjiley!
