Princess Twilight Sparkle helped Pinkie Pie clone herself to finish a giant gingerbread castle. Twilight's going to identify the clone, with 𝑠𝑐𝑖𝑒𝑛𝑐𝑒. But somepony isn't happy.
(Inspired by and based on the image "Toilet Diving" by ToisaNeMoifs for the 2019 Artist Training Grounds. Contains a pony being flushed down the toilet in comedic, cartoon fashion.) Rainbow Dash gets roped into flushing Pinkie Pie down the toilet.
One would think that digging up an old time capsule would be an enriching opportunity to learn about the past, but maybe some things are best left buried away.
When Pinkie Pie learns that Twilight might be using sweetener as a sugar replacement, she does the only reasonable thing: investigate thoroughly and not jump to extremes.
(A collab with Latecomer, open to all authors. Stories should be SFW with some potential PG content, rated Teen to be safe.) A collection of stories involving various characters undergoing potty training, to varying results.
The more things change, the more they stay the same. But when Twilight suddenly loses her tail, and then Pinkie lures Applejack into a Pie trap, and finally Rarity pranks Rainbow? How will Ponyville ever... no, wait. It's just another normal day.....
