Don't let a drop of that red-hot liquid touch Mickey or you'll have to start all over again.
Always try to drain this deadly liquid off the screen.
The rain clouds in Where's My Mickey? can be filled up with water again, as long as they pass beneath or through a water source.
You need to carve very fine paths for wind to travel through. If it hits a curved corner, it will follow around that corner, but right-angles can stop the breeze cold.
The red liquid is an obstacle in most levels, but it can also provide an advantage as it can be used to take out the organic branches that sometimes block access to stars and Mickey himself.
If you need more of that destructive red liquid, simply add more water from a nearby source. This can be particularly useful if you need to clear an obstacle, but don't have quite enough juice to finish the job off. Don't create more red water than you have to though, or you may find yourself with a serious drainage issue.
