Foals. Everypony starts out as a foal. Foalhood is a time of happiness, in which ponies enjoy life with no worries and no sorrows. But not all ponies get to enjoy their foalhoods, having to put them aside for whatever reasons, whether they wish to or not.
The sad fact for those ponies is that no pony gets a second chance at foalhood.
At least, until now.
