Teenage Mutant Ninja Turtles/Items

In the NES version, items are replenished after you leave an area, so you can take the same slice of pizza over and over. This is not necessarily true of other versions of the game.

Weapons

Each weapon upon being picked up will supply 20 of that weapon.

Shuriken	Triple Shuriken
Does 1 bar of damage. Travels all the way across the screen.	Triple shuriken - Same as shuriken but you get a three-shuriken spread. Since they're better than standard shuriken, they're less common.
Boomerang	Kiai
Does 1 bar of damage. They only travel a short distance before going in reverse. If you catch it, you regain it. If you don't, it travels across the screen exactly as a shuriken. If you switch characters and catch the boomerang, that switched character will obtain the boomerang, replacing other inventory.	Does a whopping 2 damage. These scrolls only appear in certain locations and cannot be retrieved by enemies, unlike the other 3 weapons. They travel across the screen and covers a wide range. The best weapon in the game.

Items

Pizza Slice	Half of a Pizza
Grab a slice of pizza to recover two bars of your health meter.	Pick up a half of a pizza to recover four bars of your health meter.
Whole Pizza	Rope

Used to destroy barricades or Roller Cars in area 3. Each missile item gives you ten missiles.	Kill enemies on contact when this is in effect. Used automatically when you touch it. They are most extremely rare.
