The Unbreakoball: Seriously, what's the deal?

Back on June 4, I reviewed The Unbreakoball. I  mentioned that Elka was scared of it, or at the very least, displeased. I also speculated that perhaps it would work as an outdoor toy.

We had a brief interaction with a toddler this week, where the little girl threw/dropped her basketball to Elka, who obliged by pouncing it, and dancing with her paws on either side of it, trying to pick it up. Everybody was delighted, I picked up the ball myself after a few minutes, and everybody went home happy. Unbreakoball outside then, I thought. This will be great!
