what a tasty tennis ball!

 Apparently we're missing some tennis balls for Sailor to chase 

 and we happen to have a plethora of pears falling from the pear tree...

Sailor has found a pear to be an absolutely divine substitute for a tennis ball.

His stomach seems to be a little more iffy about it though...

"Hmm... it's green, it's pretty round for the most part.
It doesn't bounce, but it must be some species of a tennis ball.
It'll do."

Sailor is so intent on this pear-tennis ball hybrid that he's not even aware
of how close Prairie was to stepping on him.

"This is the most scrumptious tennis ball I could ever dream of chasing.
In fact, I shall not even chase it. I'll gnaw on it for hours on end instead."
