King of N.Y:
Stay on the treadmill for about 1 min and you will recieve 15 coins.
With Alex, when you're at the top, jump through all the rings when they are together to recieve extra coins.
With the penguins use the fishing rod to recieve these coins.

Escape:
At the beginning kick the elephant statue and jump on the switch to reveal a secret room.
When you're at the part where you hit the trolley at 4 guards, turn south west to find another room.

N.Y chase:
Hit 25 cars (i think) with Gloria.
With Melman at the construction site use the elevations to raise yourself to the right side onto a platform. You'll see them easily anyway.

Mutiny:
Hit dartboard with darts.
With the crane, lift up the gold coins you couldn't get before.
Before setting off the toilets, go in there to find some extra coins.
Open some lockers. Don't just do this once, open them a couple of times to get extra stuff.
Before entering a room above deck (i think it's the captains room) go around the back to find extra coins.

Jungle:
Keep scaring open clams until they disappear.
Take the bees to each flower to get 5 coins from each. Try not to miss any!
Don't forget the rings!

Save the lemurs:
I don't know any secret ones here they all seemed so obvious. Just kick all the stalagmites for some coins. Don't forget the clams either.

Banquet:
Can't help much with this as i'm missing 10 coins myself.
Go down all mud slides.
Jump through all rings.
Scare all clams.

Coming of age:
When on the floor getting the last worms go right the way around to get all the coins.
Get 60 moles. If you hit them quicker you get higher points for hitting 1! Prize:15

Back to the beach:
Again, i'm missing 5 coins.
Kick the tree by the turtles a few times to gain 5 coins.
Kick all clams.
Use melmans heli power to get more off the ledge.
Scattered around the croc pit. USE MARTY AND NOT GLORIA! (game error)

Marty to the rescue:

Kick the red plants.
Kick the stalagmites.
Watch out for some going down the water slides.
Make sure you get 40+ fruit! (i don't think you get coins though)

Final battle:
I wouldn't think you'd need help with this but for the idiots:
RUN AND JUMP AROUND THE ARENAS TO COLLECT THEM!

Don't forget to complete the arcade games and beat all the high scores on everything. Check goals.

If you know which ones I don't have, please post them next to this as I am really confused on where they are. Thanks.
