Mari took a can, but didn't open it. She'd just sort of it between her two more humanly-propotioned hands, grinning like mischief while she watched Zecora and Peridot struggle.

The instant the Ring Master returns, though, her smile... well, it doesn't actually leave for long. But it does vanish for a moment. And it comes back a lot less toothy.

Wordlessly, she pulls the tab with a loud psshhhhhhts, at least one eye allocated to each other supervisors. Two are on the RM.

The rest focus on her pop.

...she can feel the carbonation in her nose even without drinking it.
