below are the diffrent items in the game
banna's are quite usefull you can get them in a group of 5 banna's or just 1 single bannana you can throw them ahead by pressing up and letting go of the trigger or pressing the trigger
Green Turtles are my favorite item they come in pack of 3 and 1 since i aim good i like me these shoot strait ahead unless you pull back on the joystick and let go they will shoot backwards this only works when you have 1 turtle not 3 they are very very usefull
Red Turtles are very good they are homing turtles they lock onto the nearest target and shoot strait for them they are quite good they are found in groups of 3 and 1 (note groups of 3 are only found in racing not in battle)
Fake Boxes are good too trick people with if you lay them where other real boxes are they might go for the fake box and get blasted into the air they are good for blocking reds off your butt too! banana's do this also
Mushrooms Are found in groups of 3 and 1 they boost you ahead letting you pass others easily
Super Mushrooms are just like the regular mushrooms they boost you ahead but you can use a super mushroom repeatedly but it dissapears quickly so use it as many times as you can befor its gone
stars make you completely invulnerable too Green Shells ,Red Shells,Banana's,And fake boxes and other stars they let you go a bit faster than you normally do and if you hit another player they go blasting into the air stars wear off quickly though
Purple Spiked Turtles are really good they are only found in racing it homes in on the person in first place and it can also hit other players along the way if they are in its path and if the person in first place has a box or banna or greens or anything protecting him the spiked turtle will get rid of it and then hit the person and if it hits someone elce along the way it wont die till it hits the one in first place!
when you use a thunder bolt everyone but you and the people with ghosts or stars on are turned really little so they can run into each other and squash each other and you can squash them flat also but they turn big again soon
when you use a ghost you are invulnerable too everything even stars but they wear off incredibly fast and when you use one
