On world 2, cross the lake and you should find 3
gobbos walking around. Get their attention and they will throw snowballs at you. You will not lose any hearts.
When you get to the part in level 5 where you have to jump across the broken bridge, don't. Instead, just go around the pit. You will see a box. Jump onto the box, but don't stomp it. Instead, turn to face the ledge on your left. Triple jump from the box onto the ledge. By doing this, you will be able to skip the cave with the breaking platforms. If your aiming to get the golden gobbo though, just go through the door, jump onto the platform and kill the dantini, then jump onto the ledge. Find the place where the platform with the blue crystal is on. Throw the gobbo at the platform to get the blue crystal. Now, retrace your steps and go through the door. Now continue with the rest of the level.
Hold A and S and run and you will do a flip and then you will do a big jump.
Push the ice block, make sure it's fireballs hit

In larry lamp, you actually have to PUSH the BIG iceblocks over the lava holes. if the fire hits the big one and it goes small, you just throw it into the lava and it melts.
