DanvilleGeorge's 55 is the 10th member of the Step Squad as she's the sum of 1 to 10. She can also be a soccer team of eleven 5's because she's quintuple 11.

TSRITW's 55 is an athlete whose specialty is climbing up and down stairs. She is not only a Step Squad of ten members, but also two 15's and a 25.

ThatGuy30722's design of 55 is a football coach. She's 5x11, so she's a mentor figure like 5, but football-themed like 11. She breaks the team strategy into 10 steps, and her whistle is shaped like a Fibonacci spiral, which is an Easter egg, as she's in the Fibonacci sequence.
