Yoyo, in his green crewneck sweater, leaps between cushions pretending to climb walls, while nearby Lulu happily stacks colorful blocks into a tall tower on the rug.

A small toy robot on the shelf suddenly glows and hops to life on its own, startling both children as it toddles forward, arms whirring.

The robot's spinning arms accidentally knock the block tower into a cage-like heap around Lulu, trapping her; she pushes at the blocks, unable to get free, eyes wide with worry.

Yoyo's face turns determined; he dashes up the wall using a bookshelf as a springboard, vaults clean over a toy chest, and lands in a heroic crouch facing the robot.

Yoyo flings out both hands as if shooting webs; glowing thread-like strands burst from his fingertips and spiral around the wobbling robot, cocooning it completely until it topples over, harmless.

Yoyo pulls the blocks away one by one and helps Lulu climb free; she throws her arms around him in a grateful hug, gold cross necklace glinting.

The bedroom door bursts open as balloons drift in and confetti rains down; Lulu claps and points at Yoyo, who looks around in delighted surprise at the sudden celebration.

Yoyo and Lulu dance together amid floating balloons and drifting confetti, both laughing, the wrapped-up toy robot wiggling harmlessly in the corner as part of the fun.
