This is the sign for Brincadeira (toy) in Libras (according to the writing on SignPuddle)

http://www.acessobrasil.org.br/libras/ (if one looks up brincadeira on this public LIBRAS website, the simultaneous line, I believe to be wrong.

I have added brincadeira with alternating motion to the SignPuddle. I believe the other two signs need to be corrected. Note the hands move one and then the other, like a bicycle, not a rowboat. The difference is the simultaneous line.
