How do you move the truck on Cryptids Island?

Answer 1

Let some air out of the trailer tires so that it will fit under the bridge. Click the left tire then click and hold the valve stem until enough air escapes. The driver gives you a digital camera.

Answer 2

At Loch Ness, the driver's trailer cannot pass under the bridge. Click the tire on the left, then click the valve stem (arrow) and hold it for a few seconds until enough air escapes. The driver will give you a camera.
After talking to the man who needs help, click the front left wheel to get a close-up view of it. Then, you have to move the mouse cursor rapidly over the air inlet of the tire to deflate the tire so that the truck can pass under the bridge. You'll receive a camera as payment for help.

Answer 3

You just have to let some air out of the tires, to lower the trailer a little so it will pass under the bridge. Click the left side of the truck, then click and hold the valve stem until enough air gets out of the tires.

Answer 4

The truck isn't stuck in the mud -- the trailer is too high to pass under the bridge. Let some air out of its tires so it can fit. (Click the left side tire, then click and hold the valve stem until it's done.)

Answer 5

Talk to the driver who can't get under the bridge. Click the left side tire, then click and hold the valve stem (11 o'clock position on the tire) until the air gets out.
