Create a standalone animated SVG of a pelican riding a bicycle from left to right.
Requirements:
- both bicycle wheels must rotate naturally
- the pedals and crank must rotate
- the pelican's feet must remain connected to the pedals throughout the cycle
- its legs should move naturally with the pedals
- the body should subtly respond to the pedaling motion
- the background should scroll to communicate forward movement
- include controls to pause and resume the animation
The final deliverable must be a single SVG file with no external dependencies.
