Two best friends who couldn't live without each other. These two friends see each other every day and they usually partake in the sport of synchronized swimming, and are usually seen as odd by their teamates. One of the best friends might be seen as somewhat lesbian or a sexual predator, as she tries to touch her twidler mate in inapropriate places.
