Dinky is the fanon daughter of Derpy Hooves who appeared in Winder Wrap up and that's about it. I wasn't really a big fan of Dinky until I saw all of the heart breaking, emotional, snuggly fan work of Dinky and Derpy and how someone with a mother like Derpy would cope in Ponyville. Though until there is a canon reason for a pegasus to be able to birth a unicorn, I'm assuming Derpy just adopted Dinky.
Ack, now with Sweetie Belle I simply am dying of cute at the kid ponies. I need the whole Cutie Mark Crusaders now.
