A fully functional spaceship, featuring three lighting modes, lithium-battery charging, jet propulsion, sound effects, and a throwing disc launcher.
Backstory:

Only in the absolute darkness of deep space does that ring of purple light awaken—

not to illuminate, but to listen.

To listen to the ripples in the vacuum, to hear the whispers of dark matter,

and then to transcribe those poems beyond human comprehension

into a series of pulses, sent toward the void beyond.

They say the mission of Yoying-5 is long over.

Yet on certain moonless nights,

the veteran technicians at the base can still pick up

the intermittent…

echoes of light from the depths of space.
