A ringing sound filled the air, and Lili opened the door. On the threshold stood a tiny box, adorned with a colorful sticker that read: "Grandma's Workshop". Lili knelt down and unpacked it. Inside, a palm-sized, silver-colored robot seemed to smile at her. On his tummy, a shiny dot blinked.

— Beep! — chirped the robot.

— You will be Spot — laughed Lili. — Welcome to our place!

Spot had two little wheels, like roller skates, and a soft antenna that wobbled left and right. Behind a small door on his back, a felt-tip pen fit perfectly. Lili carefully pushed in the pen.

— Will you draw for me? — she asked.

Spot turned around, his shiny dot flashing vividly, then he started off: beep-beep, zoom-zoom! On the sheet of paper, he drew a curly line, a spiral, then a big smiling head. Lili cheered.

— Let's make a road for you! — she said.

In the room, Lili glued colorful arrows on the floor. The red arrow meant: move forward. The blue circle: turn. The yellow square: stop and peek around. Spot watched, his light-dot nodding with a tiny flash at every signal.

— Ready? — asked Lili.

— Beep! — came the answer.

Spot sprang forward. He followed the red arrow, turned at the blue circle, and truly stopped at the yellow square. Lili clapped.

— You are really clever!

At that moment, something thudded softly from the kids' room. Lili ran to investigate. Rusty, the plush fox, had slid down from the corner of the bed and scurried behind the high bookshelf.

— Oh, Rusty! — Lili bent down. But her arm was too short, and the gap was dark and dusty.

Lili looked back at Spot.

— Will you help?

— Beep-beep! — answered the robot, blinking significantly.

In front of the shelf, a wet spot glittered on the carpet. A dripping rubber boot had left a wet spot there. Spot's wheels spun carefully but slipped on the water.

— Wow, this is a puddle-track — said Lili. — We need a bridge!

Lili quickly took out two wooden blocks, a wooden spoon, and a few train track pieces. The wooden blocks became the pillars. The wooden spoon and the tracks became the bridge. Carefully, she laid the bridge over the puddle.

— Try it! — she encouraged.

Spot pulled himself up onto the bridge: beep-beep, zoom. He rolled stably in front of the shelf.

— Wait, it's dark in there — said Lili.

She lifted a tiny flashlight off the keyring and, with colorful adhesive tape, fastened it to Spot's antenna.

— Now you can see.

— Beep! — the light glinted.

Spot disappeared under the shelf. Lili heard his wheels whirring softly: shh-shh. The flashlight's beam danced in the dust. Rusty's ear flashed into view but got stuck in the corner of a book.

— A spoon-arm is needed! — Lili declared.

She took a small plastic spoon and fixed it to Spot's side, creating a clever robot arm. Spot tried to push Rusty, but the light on his tummy began to dim.

— Oh, his power is running out!

Lili picked up the charging cord, but the socket was too far, and the cord was too short.

— What to do... what to do? — she drummed her fingers. Then an idea sparked in her mind.

From the drawer, she pulled out a small, blue pocket charger. A grinning lightning bolt was drawn on it. Lili plugged the short cable into Spot's back and fixed the pocket charger to the top of the robot, like a small backpack.

— Will it work like this? — she whispered.

— BEEEP! — Spot's voice rang out happily, and his light-dot radiated strong, warm light.

Spot carefully ducked under Rusty, and with his spoon-arm, lifted him a bit, then slowly and patiently started pushing. Rusty's body whooshed out from the gap, sliding and softly plopping into Lili's lap.

— Hurray! — shouted Lili, hugging Rusty first, then carefully Spot too. — Thank you, my friend!

Spot turned around and, with the felt-tip pen, drew a big smiling face on the floor, next to it three little hearts. The light on his tummy pulsed happily.

— What is all this shuffling and beeping? — Mom poked her head in.

— Rescue mission! — said Lili seriously. — Spot saved Rusty.

Mom smiled.

— Smart ideas and clever wheels.

Lili cut a small sign from cardboard and drew on it: "Rescue Robot". Then she glued it on Spot's side.

— Tomorrow, we'll build a garage for you, Spot. And a new road with arrows, curves, and tunnels!

Spot danced a little bit on his wheels.

— Beep-beep ho-ho!

— Ready? — asked Lili.

— Ready! — answered the robot, and he already rolled off to follow another glittering arrow, ready to draw a new adventure into the room.
