You can use any kite except the kite surfer at Kitty's Kites.
But to get the Surfing kite, you need to provide some heavier line. Get the $5 bill from the tree at the mansion, and buy a sports drink for the thirsty gardener. Use his shears at Cliff Park to cut loose the hot air balloonist. The nylon rope will let you get the KiteSurfer X-250 and go kite-surfing to the left of the lighthouse.
the kite store on main street
Get on the west coast and use the kite surfer
Get the kite surfer ,and get knocked out.
Take the KiteSurfer to the lighthouse rocks and use it there.
You go to the very left, on the rocks by the lighthouse.
When you get the Kite Surfer from the kite shop, go try it out at the Cliff Park (far left).
Fly it. Take the KiteSurfer left to Cliff park and surf from the lighthouse rocks.
Go into the kite store and talk to the lady, and she will let you borrow one for free (just click on any of the kites). You can return it when you are through, or it will appear again the next time you visit Cryptids Island. A kite is like a large "follower" anytime you are outdoors on the main part of Cryptids Island (not the other geographic locales). Like the balloons on Counterfeit Island, the kites lift you up, so you can jump higher. In fact, you can see the entire "Bigfoot or Bust" pedal-blimp at Cliff Park.
She is an unscrupulous fortune hunter out to profit from the cryptids she finds. She sabotages your kite surfer, then appears at the end to try to kidnap Bigfoot. (see related question)
You use the KiteSurfer at Cliff Park (on the lighthouse rocks), and you get to surf for awhile until an unfortunate occurrence.
You do. Once you have the rope, you can borrow the KiteSurfer from the kite store and use it at Cliff Park, near the lighthouse.
He is not on Cryptids Island. He is on Counterfeit Island.
