This time, you are a Teleporting Bat child, and you are chasing a butterfly. The only problem is that it also knows how to teleport! You have gotten really good at teleporting (to do so, press any key, and the bat will go to your mouse-pointer), but this butterfly is so fast! If you can stop it from teleporting (which it does when it hits a corner) for 10 seconds, your parent will be able to catch the butterfly.
Note: catching the butterfly yourself does nothing. In version 1.3, it's possible to lose. Don't run out of energy!
