Flurry Heart and Fizzlepop due to a kind hearted way of trying to help their daddy Shining Armor. They accidently turned Sunburst and Shining into toddlers. Cadence finds a simple antidote to turn them back to normal she learns that the spell Flurry Heart and Fizzlepop used had some how erased years of potty training from the two colts.

So before Cadence can turn the two back to normal she has the two colts retrained in using the potty. But both Shining armor and Sunburst become engrossed in seeing who can be repotty trained the fastest and turn it into a adorable competition.
