- Did you hear that, Piglet? Piglet forgives me.

- Piglet, you're unmelted!

- Piglet! You're all right!

- Yes. Thank you.

- Oh, no! If that's Piglet, then who is this?

- Kinda resembles Eeyore around the eyes.

- Heh heh. That was just a pile of snow.

- Oh. I see.

- Excuse me, Rabbit, but there is something I've been wondering.

- If it isn't spring and it isn't winter, and it isn't Groundhog Day, what day is today?

- It's November 13th, Piglet.

- November 13th?

- November 13th? Do you realize what this means? It's Porkypine Day! And if a porkypine sees his uncle Ralph, or a teakettle on Porkypine Day then you'll have to eat nothing but stewed vegebibbles for 3 months. 3 months!

- Heh heh. We got to find us a porkypine.
