Piglet Discusses the Origin of Thunderstorms

Hallo Pooh! Did you hear that storm last night? I spent the whole night with my blanket up to my ears imagining the most unpleasant things outside my door, and I would have come running to your house if I weren't so afraid of what might happen on the way there. You know what happened the last time I went out on a blustery day. A blustery night could only be ten times worse! I think perhaps storms are caused by giant heffalumps spraying water at each other. I imagine that they're quite angry with one another, and when one of them gets squirted it stamps its feet, and that's where the thunder comes from. I haven't figured out the lightning yet. I know you say you're a bear of little brains, but I bet you would have an idea. The storm is over and the fear has passed for now, but I'm left with this puzzle. There's a jar of hunny in it for you if you find the solution!
Semi-creatively,
Piglet
