Animated Pelican Bicycle

Original prompt

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.

Chinese translation

创建一个独立可运行的动画 SVG，表现一只鹈鹕从左向右骑自行车。两个车轮必须自然旋转，踏板和曲柄同步转动，鹈鹕双脚在整个运动周期中都保持与踏板连接，腿部随踏板自然运动，身体也应对踩踏产生轻微响应。背景需要滚动以传达前进感，并提供暂停与继续控制。最终成果必须是单一 SVG 文件，不依赖外部资源。

Expected outcome

The deliverable should be a standalone animated SVG that clearly communicates a pelican riding a bicycle forward. Wheels, crank, pedals, feet, legs, and body motion should form one coherent motion system. Background scrolling should reinforce forward travel, while pause/resume controls preserve the full animation state rather than restarting or pausing only selected parts.

Additional verification guidance

• Run multiple pedaling cycles and verify phase consistency among the wheels, crank, pedals, feet, and legs, with no detached feet, crank jumps, or limb teleportation.
• Pause the animation and confirm all moving elements freeze together; resuming should continue smoothly from the paused state rather than restart.
• Check that background direction, speed, and bicycle motion consistently communicate left-to-right travel without apparent backward motion or sliding.
• Confirm the SVG opens offline, has no external dependencies, scales cleanly, and keeps all content inside the viewBox.
