Petz: Dogz 2 and Catz 2/Make a Magic Shield

Theophilus tells you that there is only one object capable of withstanding the power of the Magic Hat, and that object is called the Magic Shield. They will thereofre need to make one, and to do that you need three important things; a Water Crystle, an Earth Crystle and an Ice Crystle. He says that you should start with the Water Crystle, which is in Bubble Caves on Monolith Isle. He then tells you that you will need to use Pursuit Sniffing/Whiskers to find it, and you can get to Monolith Isle from the pier at Dolphin Coast.

Repair the Lighthouse
When you get to Dolphin Coast, go to the pier and you will see Natasha standing next to the ship with a question mark above her head. Talk to her, and then you'll see what her problem is.

The Lighthouse is broken and most of it has fallen into the sea. Natasha asks where you were wanting to go, and tells you that you can't possibly go to Monolith Isle until the Lighthouse is fixed. Otherwise, you'd never get back in one piece! They can fix the Lighthouse, but to get it going again they need some Lighthouse Fuel. Apparently, Sai found some Lighthouse Fuel when he was on his travels, and so Natasha asks if you can go and find him to get it. Sai should still be at Lappy Lake.

When you get to Lappy Lake, go to the island in the middle of the lake and speak to Sai. He will tell you that he has some Lighthouse Fuel, but he wants something for it. This time, it isn't any of Ione's cooking, what he wants is a Swordfish. He heard you can catch them at Dolphin Coast. So, yuo need to go back to Dolphin Coast.

No matter how much you fish at the fishing pier near Warren, you won't catch a Swordfish. What you do need to catch, however, is a Sardine. Then you need to go to the sign on the beach and call the Dolphin. It will take you to the island off Dolphin Coast, and you need to fish here for a Swordfish. They are very big, so you can tell if you have caught one, but from here yuo can also catch plenty of other large fish. When you have caught a Swordfish, so long as you don't send it to the Aquarium, you take it back to Sai.

He thanks you and, as promised, gives you the Lighthouse Fuel. You take it to Natasha.

Soon, the Lighthouse is fixed and working again, and to say thanks, Natasha will take you to Monolith Isle.
