An archipelago, more than an island. You will have to go underwater and on clouds to advance.
1 - Forest level
There are two eggs in this level, one shortly after the start and the other just before the middle. Both contain an ax / skateboard / flower. It is advisable to bring a camptosaurus with you, to destroy the numerous stones you will encounter and you will have to be careful of mosquitoes, which will attack you a lot here. By killing a crow about halfway through the level, you can get a pteranodon. If you have enough life energy, after taking it you can fly directly to the exit.
2 - Underwater level
A fairly treacherous water level. There are many moving black spikes, which you will need to carefully avoid. As always, an elasmosaurus will be useful to you. More or less in the middle of the level there is an ax to collect.
3 - Mountain level
In this level you will encounter many jumping frogs and you will have to watch out for the jellyfish that jump out of the water. It is strongly recommended that you bring a camptosaurus with you, as its attack is more direct than axes and will allow you to take out enemies more easily. By killing a crow, however, you have a chance to get a blue camptosaurus.
4 - Cloud level
Despite its heavenly appearance, this level is quite difficult. You will have to make long jumps above the clouds, being careful not to fall into the void. There are also some moving clouds, which make the jumps challenging and, just before the finish line, a couple of falling clouds, which you will then have to overcome quickly. If you choose to bring a dinosaur with you, you will have to be quick, as fruit is in short supply. There are no items to collect.
5 - Beach level
The only thing you need to worry about in this level is the foxes attacking you from behind. In fact, you will encounter as many as eight, so pay close attention to the purple flowers on the ground. The slopes will make it more difficult to hit them. In the middle of the level there is an egg with a meat and, immediately after a deep depression, an access to a bonus area, where you can get lots of fruit and a dinosaur of your choice.
6 - Cave level
Another quite challenging level. In this cave there are many lava pools from which flames spring out. You will therefore have to jump with precision and timing. Before the finish there are two major difficulties: a section with moving platforms between the flames and a very long jump. Also watch out for bats that come towards you at great speed. A red camptosaurus can greatly simplify things by protecting you from lava.
7 - Forest level
Finally an easy and straightforward level. The enemies here shouldn't bother you. At the foot of a tree, immediately after the fourth spring, there is access to a secret room where you will be given a dinosaur, while just before the finish line, using a spring, you can get a blue camptosaurus.
8 - Mountain level
Similar to the previous mountain level. Here you will encounter fewer hopping frogs, but you will have to make more jumps on the moving clouds. So be careful and calculate the length of the jumps well. By killing a frog shortly after starting, you will get a milk.
9 - Vertical cave level
More or less like all other levels of this type. However, you will encounter some large rocks that fall from the platforms. A pteranodon will be useful to you, as usual. Halfway up there is an egg with a red camptosaurus and, a little further up, a milk to collect. Nothing too difficult.
10 - Cloud level
Another level set in the clouds. This, however, is different from the previous one and resembles the vertical caves. You will have to climb the clouds being very careful not to fall. If you fall, you risk wasting too much time or even dying. Watch the moving clouds carefully before jumping. A pteranodon will be very useful to you, both to pass the level, and in the subsequent battle against the boss. Note: don't bring any other type of dinosaur with you! In addition to being of little use, in the battle against the boss the dinosaur will immediately fall into the void and die automatically.
BOSS FIGHT
This boss battle is quite different from the previous ones. The boss will continue to fly to the right, while the screen is constantly moving upwards. You will then have to climb the clouds, because if you get below the bottom edge of the screen, you will die. When you reach a safe position at a certain height, pause for a moment to hit the boss with some axes. Resume climbing and repeat the procedure. The boss will attack by throwing fireballs at you, as usual. Its attacks aren't hard to avoid, but you have to be careful not to fall into the void. If you have brought a pteranodon with you, as advised, things will be easier. The best strategy to win this fight is to stay calm, not rushing to hit the boss. Keep climbing with precision and timing, attacking as much as you can and the battle won't be very difficult, even if it will be quite long.
