MLP:FIM Episode question

Which episode has the ‘origin story’ for Pinkie Pie. Where she lives with her family collecting rocks till she sees the sonic rainboom? (sonicrainboom?)

I believe Pinkie’s origin comes up in a couple episodes, one of which is the Cutie Mark Chronicles. I honestly had to consult the wiki. My pony knowledge is not what it once was…

Hope this helps! :slight_smile:

That’s the one. Thanks!
