Neighborly Curiosity

The passing of Fred Rogers gives me an excuse to ask a few questions that have been nagging me for a long time:

1. How come X the Owl and Daniel the Tiger could speak fluent English, while Henrietta Pussycat had to maintain a ratio of at least two meows to every comprehensible word?

2. What was the deal with X and Henrietta? Just friends?

3. "A beautiful day for a beauty"? Huh?
