Mouth symbols

[Rafaela Silva]

Hello everyone. Hope everthing is well.

I have 2 doubts/questions and I hope someone can help me!

1 - SW have a facial symbol for the expression "bruumm" that we do with the 
mouth, for example, when we want to imitate or explain the sound of a 
motorcycle?

2 - SW have a symbol that represents the mouth opening and closing 
consecutively? (As babies do whe they are starting to talk, like "papapapapa")

Thank you.

Rafaela
