She tries again. 

She can tumble down a different side, but she cannot produce a crack.

...

She considers this, then hops over to the two circling blobs. 

"Chiii KO!," says the blue one, launching a spinning kick hop at the orange one's side. The orange blob turns to face the blue one's new location, incidentally placing her right in its line of sight.

"Nyoki!" she chirps to the two of them. 

They don't much notice her at first, being caught up in… whatever it is they're doing.

She can wait. Patiently. And eat some more grass. 

The two blobs continue performing various athletic maneuvers of unclear purpose. The grass continues to taste like grass, which is to say fresh and restorative but no longer exciting.

If she pays attention and chirps again when they're between maneuvers, she can get their attention properly onto her.

She does chirp periodically when they look like they might look her way!

Then after a bit, they'll notice her persistence and turn to see what she's about.

"Nyo," she says, and gestures with her leaves at the still unhatched egg. 

They hop over towards the indicated egg. The blue one tries mirroring its wobbles.

She hops into the egg again. 

Hop! Hop! One at a time they copy her.

This pushes the egg around in a little circle.

She hops over to the other side of the egg and attempts to hop into it at the same time one of the others is doing so from the other side. 

A firm impact and a visible crack!

Yes!!! She does it again!!!

Cracks spread across the surface of the wiggly egg!

A squishy white blob bursts out and flops on the grass.

"Nyoki! Nyonyokiiiii!" she says, hopping excitedly. 

"poyooo~," it says, raising a tired bit of its edge in acknowledgment, then resumes its rest.

Job apparently complete, the orange blob moseys off toward one of the colorful plants.

The blue blob, on the other hand, noses up to the white one and starts prodding it inquisitively.

She considers this, then plucks several stalks of grass and lays them within easy nomming range of the white blob.
