Bibi is a little robot. It rolls on wheels. A blue light blinks. Blink-blink. Beep. Lili is here. Lili smiles. Lili waves. Bibi waves too.

A table. Here is the machine. A big screen, shiny and smooth. There is a red button. There is a green button. Lili presses it. Press, press. Bibi beeps. Beep, beep.

The screen shows blue lines. Green dots. Yellow stripes. Bibi says: bzz! The printer sings. Zz-zz-rr. Click-click. Paper comes. A little train. Lili claps. Bibi claps too with its arms.

Now we build. Bibi holds with a magnet. The screw sticks. Lift, put, clack. The tower grows. Clack, clack. Lili places one more block. Bibi holds it. Straight. Good and high.

A cable crawls like a snake. It leads light. A dot blinks. Sound tinkles. Chip-chepp-chip. Lili says: again! Bibi says: more! More picture, more sound.

Game over? No. Now, dance. Bibi spins. Rolls around. Lili spins too. They laugh. Beep, bzz, click! Bye, machine. Bye, button. Bye, little tower. Tomorrow again.
