Toy Time Galaxy

Toy Time Galaxy is a galaxy in Super Mario Galaxy. It is a playroom-themed location filled with toys that are made out of rainbow building blocks, usually acting as platforms. Colorful trains appear as a short transportation. The Spring Mushroom is found here. Mecha-Koopas also appears here. This Galaxy is located in the Engine Room Dome. This Galaxy is inhabited by Gearmos (like the one in the Battlerock Galaxy). The galaxy has a planet that is an homage to Mario and Luigi (Mario on one side and Luigi on the reverse side.) Also the theme music sounds like the one on the First level of Super Mario Bros. Also, the Toy Time Galaxy includes a kitchen-themed area.

Starting Planet
This planet looks like a circular train track with two stations. It has two trains on it; one with three cars (Usually ridden by the leader of the Toad Brigade), and the other with two cars (Usually ridden by the blue Toad with glasses).

Train Planet
This is a planet made up of many colorful blocks and gears with the general shape of a train engine, mostly identifiable by a long smokestack in the top. This planet also features pink walls with their own gravity. This planet has two 1-Up Mushrooms. One is between two vent pipes to the left of the starting point that Mario must Wall-Jump to get. The other is folowing more vent pipes to the right of the starting point over some fans. This planet is the first to have Bolts for Mario to spin.

Block Planet
This is a medium sized planet made up of building blocks and conveyor belts. This is where Mario first finds the spring mushroom. This planet has a pipe that leads two the planet's tubular inside.

Plate Planet
This is made up of a big plate, a fork, a spoon, and a bottle with a launch star that Mario must reach to move on.

Big Mecha Bowser
This is a big toy robot that is made to resemble Bowser on a large conveyor belt. It features green surfaces (much like the pink ones) that Mario can walk on. To get to the top, Mario must destroy its chest plate and its right arm. To destroy the whole robot and save the trapped Gearmos, Mario must destroy the stack of breakable stones on its head. After it is destroyed only the conveyer belt and the Gearmos remain.

Screw Planet
This is a strange metal and wood planet with a huge screw sticking through it. Mario must collect five yellow star chips here to continue. A hungry luma is also found here.

8-bit Mario/Luigi Planet
This is a very thin planet with an 8-bit Mario on one side and an 8-bit Luigi on the other. It is made up of one solid red brick with a star on it, shrinking green platforms, Flip Tiles, lava(on the Mario side), and dark matter(on the Luigi side). The Mario side has five silver stars and the Luigi side has 150 purple coins. The Luigi side only has these coins when the purple comet comes.

Dessert Area #1
This area consists of one cake, two slices of cake and a conveyor belt with chocolate bars on it. Mario needs the spring mushroom to scale those cake slices.

Dessert Area #2
This area consists of one large lemon cake, a slice of cake on a plate and a wall of white chocolate. Mario must bounce or walk around the spinning lemon cake to get to a sling star. The cakes's center is a black hole.

Frozen Dessert Area
This is a collection of an ice cream cone, popsicles,Lollipops and huge ice cubes. Mario starts out on an ice cream cone and is shortly greeted by the lone brr bit who lives there. Also the lollipops have a yellow robots that shoot shock waves. Unlike there purple or green counterparts they can't be jumped on unless Mario wants to take some damage from its spikes. The last ice cube has a cannon that will shoot Mario to the launch star.

Cake Planet
This is an over sized cake with five candles and six forks and spoons sticking out of it. Mario can go down the green warp pipe on the red spoon(one of two spoons not in the cake) and enter the inside of the planet. Mario must "blow" out all five candles by spinning next to them. This will cause a launch star to appear.

Undergrunt Gunner's Cake Planet
Tis is a large cake with a canister of gumballs on it. When Mario arrives the Undergrunt Gunner has taken over the planet and resides in his new electric cannon on top of the gumball canister.Mario must don the spring suit and spring up to the cannon in order to deliver the glass-rattling ground pound on the mole and end his reign of terror. Mario can find a life mushroom to the right of the mole and a 1-up mushroom above the mole.

Chain Planets
This is two square shaped planets intertwined. They are covered with tox boxes and flipswitches. Mario must turn the switches yellow in order to get the power star.

Gear Planets
These are three wooden gears that float around the factory planet. It is unknown whether they have gravity or not.

Heavy-Metal Mecha Bowser
Mario must traverse the galaxy until he gets to a giant toy Bowser robot, where Mario must destroy it completely to rescue the 4 Gearmos that were captured and forced to make it run. They will reward him with a Power Star.

Mario (or Luigi) Meets Mario
Mario needs to go to the 8-bit Mario planet to collect five Silver Stars. The pixels on the planet are replaced by lava, shrinking, and turning squares. The player must carefully and quickly make their way around the planet to collect the five silver stars and then make it back to the beginning to collect the Power Star.

Bouncing Down Cake Lane
In this mission, Mario will travel around an area of the Galaxy made out of giant desserts. At the end, he will encounter a slightly powered up Undergrunt Gunner, who he must defeat for a Power Star.

Luigi's Purple Coins
"Luigi's Purple Coins" is a level in which the player must collect 100 of the 150 Purple Coins on reverse side of the 8-bit Mario planet, which looks like 8-bit Luigi, within the three minute time limit. The lava is replaced with Dark Matter, Flip Tiles, and Shrinking Tiles. If Mario manages to collect 100 purple coins, he must make it back to the start to collect the Power Star. It has been officially labeled the hardest level in the game.

The Flipswitch Chain
The Secret Star of the Toy Time Galaxy. The planet containing the Flipswitches is accessed by feeding the Hungry Luma in Mario Meets Mario on the fan-type planet. In this Star, the Player will go to an area resmbeling Cyclone Stone, from the Beach Bowl Galaxy. Except, instead of simply needing to reach the end of the level, the Player needs to hit several Flipswitches covering the entire area. The main Planet the star takes place on, is two different pathways that seem to be strung around each other. After hitting all the Flipswitches, the Player will be able to get the Power Star.

Fast Foes of Toy Time
A star taking place with with a Fast Foe Comet in orbit. The player must complete The Flipswitch Chain to be able to play this mission. The Star is almost exactly the same as The Flipswitch Chain, but, because of the Fast Foe comet, all of the enemies and traps there are faster. The fact that the Fast Foe comet takes place here makes it more similar to the Cyclone Stone area of Beach Bowl, since the Fast Foe Comet star was there on Cyclone Stone.

Trivia

 * The background music for toy time galaxy is a remixed version of the "Super Mario Bros" overworld theme
 * High above the Galaxy is a wierd capsule shaped planet that the player never actually travels to. However, it should be noted that hacking the game and flying to the planet reveals it to be the tube-like area that the player can enter by using the Warp Pipe on the first mission. All galaxies that have Warp Pipes leading to 'underground areas' all share this oddity as well.
 * A miniature train is viewable in a small crevasse near the Warp Pipe, mentioned above, and a 1-Up Mushroom. It doesn't appear to serve any purpose, and may just be eye candy for the level.
