Delfina plays with her puppies

I found something!
A colourful plush egg.
What a
great prey!
I'll take it!
Catch me if you can!
Mum is running away!
Don't you want to get it back?
That's what we're gonna do!!!
I'm faster than you are!
Now, we take it back!
It's ours again!
But if it doesn't move, it's boring!
