Yozhik flies

A pink, bespectacled character in a star-shaped helmet floats underwater, initially appearing dazed, then reacting with wide eyes as a smaller character in a red suit approaches and attaches a device to the helmet, before the pair sinks into the water. The scene transitions from a colorful underwater environment with fish and bubbles to a black-and-white shot of the character looking up at a starry sky, then back to color as the character descends into a dark, leafy area.
