Found my self laying awake realising I havent drawn these two before hand so here we go.

I headcannon that Pinkie and Cheese are married (unoriginal idea is unoriginal) with three foals together. However Pinkie does have a Foal from a previous relationship with another stallion. Pinkie allways wanted a big family, the more the merrier after all right? Cheese and Pinkie started seeing each other not long after the episode Pinkie Pride and were married by the time the finale rolled around. Pinkies other foal made the decision to live with their sire, occasionally visiting their mother and step-dad.
Pinkie is a heckin floofster, shes stocky with a bit of chonk, her RL counterpart would deffo be a shetland Pony, often regarded as a big party horse in a small concentrated package. Cheese is on the lanky side for an Earth Pony, standing around 11.2 Hands at the withers (44.8 Inches) while pinkie would be quite a bit smaller at 10.3 Hands (41.2 inches). Pinkie and cheese have taken over the running of sugar cube corner as their own buisness after Mr and Mrs Cake announced their retirement.

More headcannon coming soon,  I need to start sitting down prior and writing out drafts for my headcannon as I can never articulate my ideas amazingly without prior planning
