AKA Best number in my opinion. Gender: Female Gimmick: Seventy-Seven is Seven Elevens (Get it?) and also made up of three consecutive squares: 16+25+36 (Also good friends with them). She is quite sweet but can be very shy at times.
(c) Numberblocks I didn't go with the "7 Football Teams" cliché on this one because I dislike it in general and I want to be more unique.
