5 out of 7 corgis receive coal in their stocking. They then bury that coal in the backyard. There it stays for millions of years. Heat and pressure smoosh the carbon until it finally becomes a lovely diamond. Then the bionic future space corgis dig up the diamond, sell it, and then buy all kinds of awesome future doggie toys and a time machine.
They take the cool doggie toys, wrap them in shiny paper, head back in time, and deliver them under the tree for the corgis who buried their coal. The naughty corgis get their cool future space toys from the bionic future space Santacorgis and the derpy corgi gets to play with the shiny paper.
And they all live happily ever after.
