"Certainly."
Dear me, what a lovely device! A Pokéball. Glossy outer casing, but beautifully grippable even in gloves. About the size of an orange (and just right for a child's hand, he notes approvingly). Sniff, sniff. Very little smell of its own; afterimages of a coppery-ozone volatile, an unidentifiable rubbery latex note, and cooking oil. Mmm, and not too heavy to hold. Surprisingly minimalist exterior—one might say featureless, except even its heft and shape and texture contribute to a sublimely intentional harmony. Yes, quite thoughtfully designed—at least decades of invisible work, he'd wager. And a depressable button, which he's agreed not to touch.
Now the actual mechanism...he had worked out some similar principles himself with Television Chocolate: a single magnesium-bright flash, and you can send a bar of chocolate whizzing through the air into a television receiver halfway across the world. But to do the same with a living creature, and broadcast it as large as life wherever you please—thrilling! What kind of super-compact electrochemical battery might be powering the device? Is the creature transmitted someplace else and later retrieved at will, or—oh, why hadn't he thought of the implications before?—are the bits etched onto on some kind of storage tape until they're needed?
"Tell me," he chirps. "Is the creature actually inside here, or is the ball like an antenna that transmits it somewhere else? Would it work deep underground, say?"
