Butterflies want a ride

A flower sits in the car,
Yellow Butterfly was about to come up and say hello,
Chug tug tug──
The pickup truck started moving without saying a word!

"Bicycle, help me!
Catch up with the pickup truck ahead! "
The children pedaled hard,
Jingle Bell! Keep going!

But,
How can a bicycle catch up with a pickup truck?
Why not switch to another car?
Puff puff──
Keep moving forward! …
