Garde and the Air tank [Page.2]

The Garde did as the small text on the tank told her to do, but she wonders what to do next..

She thinks for a bit then finds an idea! she remembers that airtanks are used to make ballons/belly's bigger

but she didn't see a balloon anywhere, so she just grabbed the hose, slowly placed it in her mouth, and cranked on the air tank!
