Asking the second puppy of the bunch, Dexter, to come with the Mightyena, named Richter, he told the Poochyena something important.

Richter: Hey, Dexter?
Dexter: Huh?
Richter: I want you to be a good model for the other two puppers, so don't mess anything up, ok? We are going shopping to get ready.
Dexter: *just nods*

As they went to the store, Richter got some toys, wear, and padding, pull-ups for Dexter and diapers for the other two pups, which Richter kept secert for now.

Richter: Follow me, Dexter, I will explain later.
Dexter: Umm... K.

As the two entered a bathroom after purchasing the items, Richter got the pull-ups out and took one out. The garment was indigo in color, had a Zorua on the front, star design, and moon indicator.

Richter: Stay still, I need to put this on you.

Richter slipped the pull-up under Dexter's two hind legs and pulled it up to his waist.

Richter: There you go. This should help out, as you don't have to worry about potty breaks, but if you really need to go, tell me.
Dexter: *nods* I never have worn these since I was a young pup.
Richter: I know it's quite odd, you will adapt easily soon enough.

As the duo when home, what happens next?

1. The two other puppies bully Dexter for his new padding.
2. The third pup ignores Dexter but the first pup still catches on.
3. Both pups don't mind what Dexter has and the next steps are considered.
