There are five carnival games.
1) "Strike out". This is a carnival classic. Throw balls at the moving metal plates. It can be found at the right side of you. Just besides the souvenir shop.
2) "Splish splash" This game is a bit like the "penalty shots" The objective is to throw a ball at the red button. This will make a very little (and cocky) man to fall down into a tub of water. Very amusing to show him who's the man! It can be found to your left when you enter the big area with the rides.
3) "Shooting range". This is a classic to. You use a pink rifle to shoot bottles and bad guys that moves along the screen. Avoid the girls though. It can be found at the left side of the carnival.
4) "Hight striker". Another classic. Press X constantly to get power and hit the red button with your hammer to make another red button fly up and hit a bell. It can be found to the left of "Splish splash".
5) "Go cart". Place first at five go cart races. Win the first race to gain a crash helmet.
There is also a fortune teller machine straight right of the "Strike out". He gives you some hillarious messages.
Example: Avoid useless gambling at all costs. Your lucky numbers are 36, 42, 56 and 28
