Because of the rate of enemy appearance in this stage, you may need to scroll the screen up and down several times to clear them away just so you can uncover hidden treasure chests.
In this treasure room, you will find seven treasure chests. You should still be powered up enough to crash through the treasure chest and open them all up quickly. However, be prepared to catch the contents: all balloons. If you collect every one, you will earn a very fast 70,000 points.
When you're ready to head out, you'll have to think fast. Below you is a bed of fire, and the only safety is a few blocks away. You'll have to pound on the A button to make Jack float safely over the flame and on to the ledge beyond.
There are a Mighty Drink hidden at the end door from this section on american version.
There are no secrets to be found in this section. You'll have an easy time earning the 10,000 point bonus if you collect every bomb in this stage from right to left.
