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 list given to you by the Queen shows it at X-83 Y-20, up and right from the planet Poptropica. To land, click on the planet.
On Astro Knights Island, you wait for a platform to come down to a level so that you can jump onto it. However, the 6th platform never gets lower than the 5th, so you should jump when both platforms are moving rapidly down. The 6th platform should fall right under you.
When you arrive at a planet, you click on it. Planet locations : Jungle Planet (X-15 Y-15) - upper left Ice Planet (X-73 Y-83) - lower right Fire planet (X-83 Y-20) - upper right
There are no plants to click on. You click on the lower shelf in the castle library (McM) and click the "planets" when you arrive at them. On the Jungle Planet, the elevator plants work automatically when you jump onto them.
It is visible as a small sparkle or flash of light halfway up the fountain. It only appears when you jump onto it.
Jump to each of the rocks when it is lower, even if you can't see it. For the 5th and 6th rocks, jump when both are moving quickly downward. At the top, jump left onto the volcano and enter.
One of the trickier jumps, many have tried to skip it and jump blindly from the 4th to the 6th rock. The simple solution is to jump when both rocks are moving DOWNWARD. The sixth rock will then be falling under you.
To reach the cage on the jungle planet, you have to jump across the four Phoenix eggs. Climb up the rope at left, and jump onto the eggs when the shells are CLOSED. The secret is to JUMP when the eggs are OPEN. By the time you land, they have closed again!
Shoot the alien spaceships and dodge their shots (your shield will eventually fail). On the Jungle Planet, drop down to the surface to get the Laser Lance. The springy metal flowers will throw you back up (in stages) if you stand on them. Step onto the moving platforms to go right, where you will find Sir Cador and the flying unicorn.
you get on top of the ye old romour mill sign, and jump on the wind mill blades and make the wind mill move. Jump about 4-5 times. Then, jump onto the middle of the windmill, and from that jump on the roof and enter.
You hop on the lava spouts (jump from 5th to 6th while both are headed downward). Once on the last one go onto the volcano. Then climb down to the snake while avoiding the yellow air currents. Then hop over the snake and defeat the dragon by shooting an ice arrow into its mouth. (detailed solution at the related question)
You have to jump from where the Princess is, either to the left or right. Then wait until the robot shoots with his laser (he has to be right below it when it falls). The lower gravity there lets you jump farther : you can jump from the robot suit to the pedestal, and to either hanging chandelier.
