Items
Anklet

Good for one room only, the anklet allows Mike to jump up to two spaces instead of one. Apparently anklets turn your shirt orange as well?

Used to start a fire. Easier than rubbing two sticks together.
Big Apple

It's delicious, but nothing happens.
Big Heart

These will increase Mike's total hearts by one and then refill all of your energy.
Blue Magic Cube

Mike feels a strange power flow into himself. Fully increases his life level!
Bottle

A bottle that has washed ashore. Inside is a letter from Dr. J and another ID code. Luckily Mike is the one who finds this or his uncle would still be lost.
Coconut Milk

A sip from this jug restores Mike's hearts to full.

Double Heart

Picking up one of these refills two of Mike's hearts.
Fresh Worm

This ID code is given to you by Dr. Jones' assistant, Baboo. It allows Mike to start the engine of Sub-C.

Picking up one of these refills four of Mike's hearts.
