“There it is!” Pitir shouted excitedly. The little boy pointed to a tall, gleaming gate directly ahead, which only seemed to grow taller as the group approached.

“Welcome to DynaPark!” a voice cheerfully greeted from the loudspeaker over the entrance.

“Oh my gosh!” exclaimed Eva, her walking turning into a bouncing skip. “This is gonna be so much fun!” The tail on the young girl’s Eevee kigurumi swished back and forth with her energetic movement, giving the impression she was wagging it herself.

Pitir started skipping, too, the long ears on his Pikachu kigu flopping around as he did so. “Yeah! DynaPark! DynaPark!”

“Kids, kids, settle down!” the man holding the children' s hands said with a tired smile. “We’re not even inside yet.”

Both kids resumed walking, but their steps were still bouncier than normal.

Eva turned to the man. “Thank you again for taking us, Uncle Dimitri!”

Nodding enthusiastically, Pitir added, “Yeah, thanks, Pop!”

“Hey, a deal’s a deal,” Dimitri replied. “You kids got good grades, so now you get big-time fun with your Pokemon.”

“Yay!” both children said in unison.

As the trio entered the park proper, they were greeted with a vast vista of manicured lawns and fancy topiaries. Various Dynamaxed Pokemon frolicked and played in the distance, the rumbles from their titanic steps audible from the entrance area.

Pitir and Eva looked at each other, grinning widely, then turned back to the playground of giant Pokemon; they started bouncing again.

“Now, before you two go play with your Pokemon,” Dimitri said, looking at each kid in turn, “Do either of you need to go potty?”

“Uh-huh!” Pitir replied as he looked down and spread his legs.

“Yup!” Eva said with a nod as she squatted.

A quiet hissing sound became audible as both kids peed. The bulky outlines bulging out the butts of their onesies became more pronounced as their diapers grew puffier.

Dimitri facepalmed. “That’s not what I - “ He shook his head. “Nevermind.” Under his breath, he added, “Well, at least they aren’t messing...”

”Hey, Pop,” Pitir said, straightening his posture as he finished relieving himself. “We can let our Pokemon out now, right?” 

“Yeah,” Eva added as she stood back up. “Please, can they play now?”

“Yes, of course,” the man replied, stroking his beard. “That’s what we’re here for, after all!”

The kids cheered, then eagerly reached into their respective pockets; each one pulled out a cherish ball and threw it.

“Time to play, Blondie!” the blonde-haired boy called out.

“Playtime, Brownie!” the brown-haired girl shouted at the same time.

Blondie appeared before her trainer in a flash of light. “Pika pika!” The Pikachu had a curl of hair that swooped up in the front, and she wore a pull-up that matched her pokeball.

“Vee vee!” Brownie cried excitedly as he popped out of his ball. The Eevee had a pronounced swirl of hair on his forehead; his tape-up diaper matched the other Pokemon’s in color.

“Oh, you kids will probably be needing these,” Dimitri said as he fished a couple of Dynamax bands from his carryall and handed them out.

“Thank you!” both kids said at once. They put on their bands, wearing huge grins as they did so.

Dimitri nodded, then pointed to the grassy expanse. “Now, run along and have fun! I’ll be here if you need me,” he said before sitting down on a nearby bench. 

The children and their Pokemon ran out onto the grass, hopping and leaping excitedly. When they were far enough from the entrance, Pitir and Eva separated, making sure there was enough space for their Pokemon. They then looked at each other and nodded in agreement.

“Gigantic-Max time!” Pitir called out as he raised his right arm.

“Gigantamax time!” Eva corrected as she raised her left arm.

Timing their movements exactly, the cousins simultaneously pressed the buttons on their bracelets.

Blondie and Brownie each became engulfed in glowing red energy, before growing enormous. The Pikachu and Eevee each turned into their Gigantamax forms: Blondie grew fatter, her tail lengthened, and red clouds appeared above her head; Brownie’s neck fluff puffed out and became fluffier, while red clouds started circling his right ear.

“Piiii!” boomed Blondie.

“Veee!” Brownie yelled out.

Pitir’s green eyes filled with wonder. “Whoa, you’re so biiiig, Blondie!”

Eva’s brown eyes, while filled with wonder, too, were also filled with apprehension at being so close to such huge Pokemon. “Careful, Brownie!” she cautioned her Eevee companion, “Please don’t squash us!”

“Eeeeeveeee!” Brownie replied with a nod.

The group ran around and played for a while, the ground thundering as the Gigantamax Pokemon moved.

Suddenly, Blondie stopped moving. The gigantic Pikachu squatted; a loud rushing sound filled the area, as her pull-up puffed out in the bottom. “Piiiipiiii!” she loudly sighed in relief.

At the same time, Brownie had also gone into a squatting position. “Vee…ng…vee…” he grunted. Booming crackles and squishes sounded out as the seat of the super-sized Eevee’s diaper bulged out and sagged.

“Yucky!” Eva whined as she pinched her nose.

Pitir gagged.

Dimitri, watching this unfold from a distance, sighed heavily. “Man, why’d I sign up for this…?” He shook his head, muttering, “That’s the last time I make a bet with my sister!”
