The horses - Penny gets a reward for calm behaviour!

The big birds - maybe geese? Penny watches quietly.

The river lookout - Penny is bored, her human is entranced.

The swim with the ducks - Penny chases a thrown stick, the ducks mill around in hope of being fed.

Then a nice roll on the wet stick to absorb the smell.

And, just to cap off a really good walk, some (a lot of) scavenged poo, green and delicious-looking, before Penny's human wakes up what's going on.
And later that evening, the black, tarry poo that leads to the lengthy bum-wash, and the semi-sleepless night as the human waits for Penny to show signs of ill-effects.
But, so far, no bad effects, thank goodness.
