When the space sharks are chasing you, get close to the black hole and circle around it while not going in. The sharks will be caught and dragged inside.
they are around it and you have to lead them 2 the black hole
There are no fish on Astro Knights Island. There are Space Sharks around the Ice Planet at X-73 Y-83. To defeat them, shoot them and lure them to the Black Hole at X-85 Y-47. (see related question)
you get them in the black hole
ya just take them to the black hole around the other planet
x83 y49
You shoot the space sharks, and run away slowly. They follow you, so if you get them near the black hole, they get sucked in. (Black Hole is up and left, at X-85 Y-47.)
The black hole is at X-85 Y-47, up and slightly to the right from the Ice Planet. Its only use in the game is to dispose of the Space Sharks. (see related question)
The fish that you need to throw at the space sharks on Astro Knights Island is located in the Seaweed Restaurant. You can find it inside a barrel on the left side of the restaurant. Just click on the barrel to pick up the fish and use it against the space sharks.
Shoot at them or pass in front, but don't get chomped. You have to let them stay close to keep them following you. Move ahead, then let them catch up.
You have to goto each of the planets and find the knights some of the planets are quite challenging so I suggest you start with the green or red planets the ice one is hard to get into because you have to lure the sharks in to a black hole Well Goodluck with your poptropica adventrue
The space sharks are "swimming" around the Ice Planet (X-73 Y-83) on Astro Knights Island. If you keep going toward the bottom right corner you will see the alert that says "Warning: Space Sharks ahead." To get past these sharks and reach the planet, you need to shoot them (singly or all three at once) until they chase you. You can very slowly lead them up and right to the Black Hole at X-85 Y-47, where you can lure them into the hole, ideally without falling in yourself.
You have to get near a space shark and lure it over to the black hole located to the north of the ice planet. Do not go into the black hole yourself, but circle it until the shark has gone inside. Do this for all three sharks and the way to the planet will be cleared.
