The Castle of Dr. Brain/Planetarium

Welcome to the planetarium. For a second, it looks like we've been wandering through the castle so long that night has fallen. Though on closer inspection, it seems that the sun is still out, so who knows what's really going on here. The first puzzle here is in the sky. Click among the stars to bring up the constellation puzzle.

Constellations
The goal of the constellation puzzle is to recognize and point out certain constellations by clicking on the stars that make them up. Clicking a certain star will turn it "on" and it will become yellow, while clicking it again will turn it "off".

The constellations are the same on each difficulty setting, though the correct stars stand out a little more in Novice than on Expert and nice red lines will appear between the correct stars. From left to right, the constellations are Perseus, Ursa Major, Cancer, and Orion.

When a constellation is picked out correctly, with no other stars turned on, the blue outline of the constellation form will appear around the selected stars and you will be able to move on to the next constellation.

When you have located all the constellations, the locked cupboard at the bottom left of the screen will burst open and an alien in a weird little UFO will fly out and buzz across the screen randomly. You're going to have to catch him by clicking on him to "set him free" and move on. When you do, he'll dart off to the right and the match puzzle will start.

Alien Homeworld Match
The goal of this puzzle is to match the alien species with their respective home planets by flipping over the correct cards. Though this is a memory game of sorts, you have an unlimited number of flips and number of flips does not affect final score. The correct matchups are:

Amphiton - Oceania Maston - Graviton Giras - Veldta Geoids - Magma 4 Stiger - Stroud Mechroid - Metallica Moleri - Hollucidar Winged Icarion - Aerious

Solar System
When you have matched up all of the aliens with their homeworlds, you'll get an award for getting these aliens all home, as if they didn't know what their home planets were in the first place. At any rate, when they are all matched up, the room will shake and a shiny black mirror-like object will rise up out of the floor. It may not look like it, but this is the door into the next room. Before you can enter it, however, you must solve the planet puzzle.

A window will pop up showing the solar system, complete with planets flying around the sun. You'll have to click on the planet's name at the bottom, then on the planet it represents on the top. The only difference that difficulty makes is the speed of the planets. On Expert difficulty, Mercury rotates around the sun like a ceiling fan.

In case you weren't forced to memorize it in first grade, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Yes, apparently this program refuses to believe that Pluto was ever demoted, so that's cool.

When all the planets are marked and colored, Dr. Brain will insult your memory skills, then the room will go white and you will find yourself in Dr. Brain's office.
