A Helpful Note To Some Of You
Some people can only find 5 golden coins, the five obvious ones, here is the finding for a sixth coin:-
When you are selecting your level go to the hippo stage. When you enter the hippo level, you will find a model of a hippo blowing bubbles, jump into a bubble and float the whole way of the level in the air. At the end of the level, insted of exiting through the regular door, you will exit through a door above it, which is normally unreachable without you floating through the bubble, go through it and you will come to a space stage, which is hard, if you complete it you will get the coin.
Beware though, when floating through the air in a bubble avoid all enemies and the water coz the bubble will just pop.
And another thing, whenever you want to get to the space stage, you will alaways have to go through the bubble in the hippo level first.
Beat the Level Bosses
Space zone: you will have too aviod the blast and try too stomp him on the top
Marco zone: you will find a ratt but BEWARE it will try too ram you he will alwayes come from the same tunnel that he goes in.
Mario zone: Their are 3 pigs if you have the plant you can shoot them 2 times and stomp on them once it will die
You can shoot all bosses whith the firebals
Beat the Bird Boss
In the last level of the Tree Zone, try to get the flying cap. Once you get to the Bird Boss, jump(not high). If your timing is good, you should come down right on his head. Do this 3 times.
When you are at the place where there is 3 tubes a,b, and c press select the mario will appear small and it will say easy mode at the top!
When you get to the Hippo level, you see the Hippo blowing bubbles. Pass that and go into the water. When you are in the water, go LEFT. As you keep going, you are in a tunnel that is in the water. When you get to the end, you will see a little question box. When you hit it, a sack of money will appear, which contains 50 coins. Then go back to the Hippo blowing bubbles and catch a ride in a bubble. Go up as far as you can and a while later, when you get four coins from the sky (that is sort of like an alarm), you will fly through the big cloud that you are in. When you get to a smaller cloud, just outside of the big cloud, go under it and keep going up and down in the bubble until you hit an invisible box in the cloud, another bag will pop up and in it is another 50 coins. You can do that level over and over again each time earning 104 coins.
Extra Life and Extra Coins
To get one extra life, first go to the hippo level. Get in the bubble and float along. After a while, you will come to some spiky enemies that stay in one place, but wobble when they see you. Coins go around them. Pass the first one and when you come to the second one, float up directly beneath it. DIRECTLY BENEATH IT!!!! Or you will pop your bubble. The spiky guy will die and a heart will pop and of a box. Get it.
(SAME LEVEL)You can get 2 bags of extra coins. The first one is underwater. Jump off the ledge where you start, and go to the left a lot. You will see a ? box. Swim underneath it and a bag with an M on it pops up. Get it, and you will get 50 coins or something. The second is in the air and kinda hard to find. Float in a bubble until almost the end. Stop when you see clusters of ? boxes in threes. In other words, [?][?][?], like that. Float up and to the left and you will see a cloud shaped like a rounded cross, it has four rounded sides. You could also say it lookes like a big, fat clover. Anyway, float up slightly right of the middle of that cloud, and a money bag should appear on a box. You will get 50 coins.
