Breathe in rhythm

Growney is running! Hold your finger down to breathe in, and let go to breathe out. Don't let the oxygen run out!

Growney is running faster. The muscles need more oxygen, so breathe faster!

Oh, the oxygen ran out! Breathe faster.

When you run, your muscles need more oxygen. So you breathe faster and deeper.
