Jace bounded out the backdoor, his eyes wide with excitement. Behind him, Addy followed, her steps more measured but equally eager, while their dog Bella darted ahead, her tail wagging furiously. "Come on, Addy! Let's find some treasures today!"

Addy traced a line on the map with her finger, her eyes focused intently. Bella sniffed around the blanket, curious about the day's adventure. "Here... start... here," Addy said, her voice soft but clear.

Jace pulled out the chest with a triumphant grin, dirt smudging his hands. Addy watched, her eyes sparkling with delight. "We found it, Addy! We really found it!"

Addy unfolded the note carefully. Bella sniffed the marbles, her nose twitching. "Look... colors... like a rainbow," Addy murmured, tracing the marbles with her fingertips.

Jace mimicked the shapes on the paper, drawing in the dirt with a stick. Addy nodded, understanding their secret language without words. "We make the best team, Addy," Jace said, his voice filled with affection.

Addy leaned against Jace, her head resting on his shoulder. Bella snuggled closer, her eyes closing in contentment. "Brother... always," Addy whispered, her words a promise of their unbreakable bond.
