Here is a list of the secret items, and their locations:
NOTE: You must have played through a stage 3 times before special items will appear.
Stage 1:
- There is a bottle with a trapped seahorse near the beginning of the stage. Right after the crabs on the left.
- Just after the octopus near the end of the stage, there is an old fahioned diver's helmet on the ground, throw a gadget at it and then take a pictue.
Stage 2:
- On your left, shortly before the sunken ship in which you can enter, you will see an old captain's hat. You will notice that it is moving a little bit. Throw a gadget at it and then snap the picture.
- Right near the end of the stage, you will find yourself in a cavern. There will be a chest that you must throw a gadget at. An eel will emerge and then you take the picture.
Stage 3:
- There are two statues in the level of a lady. The second one will have a starfish on her face. Throw a gadget at the statue and the starfish will move, revealing a jewel.
- There is an alternate route under some ruins. Once you reach this area, you will see a large jar looking object. Throw a gadget and it will sprout limbs and take off. (Note: this is also an achievement item)
Stage 4:
- There is a robotic fish that swims by when you are nearing the Kraken area. Hard to miss. (Note: Achievement item).
-Near the end of the stage, you will see a trident sticking out of the wall a little ways towards to bottom. Also hard to miss. (Achievement item).
Stage 5:
-Right at the beginning of the stage, look to your left. There will be a crab on the bottom of the ocean floor. Throw a gadget at him, and an anchor will fall for you to take a picture.
-Easiest item to find. It is right at the end of the stage, and it is a huge statue (Of the Easter Island variety).
