Hint: Using hammers effectively
Always use your hammers in a rapid fire sort of way. If they disappear and make a strange noise, jump at that spot. Your character will get an egg which contains a level skip, inventory item or bonus level.
Hint: Collecting food
Stay low to the ground with the pterodactyl, as to collect food.
Hint: Obtaining eggs from birds
Try to shoot most birds over the ground as some of them carry eggs.
Hint: Defeating the Fern Island Boss
When you encounter the Boss, stay far enough away so it does not start attacking you. Then, start throwing hammers at him. The Boss will accumulate all the damage that was dealt.
