Unlock Secret Roper Level
In stage 7 where you start off with the heavy bag in the glass cell, punch the bag 87 times to hear a chime and wait a few seconds. Your head will be replaced with Roper's and every enemy in the stage also has their head swapped as well. This stage is VERY difficult.

Finding "Fuzzface"
On stage 6 "Assault Zone", after the Hellacopter section and right before the first ladder, there are two gravestones sitting on the bottom of the screen. Go between them and press the dodge button 7 times and it will unlock "Fuzzface", a strange and out of place creature that can fly and talk. He'll hover over you for the rest of the game and occasionally give you power ups and items, making the game much easier.

Hidden Area
Play the last level. After becoming a Ro-Bro, move to the left until reaching the left side of the screen, the move down. You will descend a hidden ladder and find an area with extra lives and two chests.
