The Sparks Nevada Theme is sung by Bradford's voice actor, Marc Evan Jackson. The theme song belongs to them from the Thrilling Adventure Hour podcast.

"When there's varmints need a catchin'
And youngins need a savin'
On my rocket steed I race across the stars.
For I've sworn by the burs of my astro-spurs,
To right the outlaw wrongs on Ma-a-ars."

"Yes, he rights the outlaw wrongs on Maaaaars!" April rang the old tune as Bradford wore a toy cowboy hat on his head.

They were in April's childhood bedroom in Bradford's home. The room was a mess of purple wallpaper, plush toys, dolls, sparkling lights, and spilled glitter. April sat in her bed in her dark pink PJs, her journal sitting beside her as her father pretended to ride a horse while still wearing work clothes.

"On the plains of the red planet I uphold the la-a-aw.
And I do it with a pair of robot fists (POW!)
For evil extermination I have wished
For my robot ropes they hardly ever miss!"

"HARDLY EVER MISS!" she shouted strongly.

"I reckon I'll be ridin' in the name of truth and justice
For as long as I can count the shootin' stars
For I've sworn by the burs on my astro-spurs
To right the outlaw wrongs on Mars.

"To right the outlaw wrongs on Marssssssss!" She laughed.

Bradford chuckled. "And I'm from Earth."

He touched his forehead and beak to hers, and April giggled.

"Oh dad, that's such a silly song. Why'd you make it up?"

He took off the dusty cap and put it on top of April's bursting toy chest. "Well, I needed a song to calm you down at night as a baby, and the words seemed to come to me easily."

He sat down on his daughter's bed and petted her head. "Who knows? Maybe I might have some adventurer blood in me yet," he said sardonically.

April giggled again, then she stopped and frowned. Bradford felt worried.

"What's wrong, sweetheart?" he asked softly.

"Well," she started nervously, "its almost my birthday, right?"

He nodded. "Right. You're turning ten soon. You're getting so tall." He put a hand on top her head, as of he were measuring her. "Soon you'll be as tall as me!" He sighed happily. "Where does the time fly?"

But April twisted her sheets in her hands. "That's the thing, dad. I know I asked about a hundred thousand times but…maybe for my birthday…can you-,"

"-tell you where you came from?" Bradford finished with a gentle smile.

"Yeah, please please please!" April jumped in her bed excitedly before her father put his hands on her shoulders and carefully pushed her back into bed.

"Such an energetic little thing, aren't you?" he teased.

She eagerly waited for an answer, but Bradford let out a long exhale of breath with a smile. "Ah dear. You know I adopted you. Isn't that enough to know?"

"Ohh, but I want to know how you adopted me. Do you know who my parents were?" She suddenly gasped dramatically. "Were they a royal family in some distant land who couldn't take care of me because they were on the run from some evil overlord who wanted to take over the kingdom?"

Her father laughed. "No, nothing like that."

She leaned forward eagerly. "Then what is it? I tried asking Mrs. Beakley and she couldn't answer me, and then I tried asking Uncle Scrooge, and he said the same thing as her!"

"Which was?" he raised a questioning brow.

"They said to ask you!"

His eyes went to the sidelines. "Mm. Yes. Of course." He sighed again. "April dear, if I must be honest, I don't think you're quite ready yet to hear it. Maybe once you're older-,"

"Oh, but could you at least just…just tell me how you found me? Or at least," her eyes became downcast as she started to fiddle with her silver locket. "At least…tell me why you adopted me?"

"Oh, April, dear…" he leaned towards her and hugged her tightly, and she returned the hug. "I loved you the moment I saw you. And when I realized that, I knew you'd be my little girl. Oh, ladybug, I didn't mean to hurt you like this. It's just…very difficult and painful for me to explain it."

"Yeah?" she gurgled, facing him again as a small tear edging at her eye.

He nodded, wiping her tear away with his finger. "But…I can tell you a little bit about it."

A smile quickly returned to her. "You mean it?"

"Mhm," he nodded, then a small chuckle rumbled in his long throat. "I made you," he tapped a light finger on her bill, "in my own personal lab because I wanted to make someone I'd love with all my heart. I took you out from there, brought you home from the ocean harbor, and you've been living with me ever since."

She giggled. "Oh dad, you're so silly."

A small bark of laugh escaped his beak. "Maybe not as silly as you think."

"Well, then, why'd you name me April, even though I wasn't born in April?"

"Because I just really liked that name."

"Aaaaand, my birthday? Are you sure that's my birthday?"

"Asking a lot of questions tonight, aren't we?" he chuckled. "Well, when I brought you in from the harbor, you looked to be about a month old, so I did the guess work from there."

"Wait," her eyes bulged. "You…you did find me on the harbor?"

He laughed a bit more, then patted her head again. "That's all for now, bug. Goodnight, April."

He pecked a kiss on her forehead, then got up from her bed.

She gasped excitedly, clutching her glittering diary to her chest as he went to turn off the lights. "The harbor! I'm a little mermaid baby! I knew it!"

He closed the door carefully behind him, listening to April's meandering talk about her being a mermaid princess with a smile. Then, a serious frown came to him, and he went down the hallway to his work-study office.
