Yoshi Topsy-Turvy

Yoshi Topsy-Turvy, also known as Yoshi's Universal Gravitation in Europe, is a platforming video game starring Yoshi for the Game Boy Advance. It was developed by Artoon and published by Nintendo. Yoshi-Topsy Turvy first released in Japan in 2004, then in Europe, North America, and Australia in 2005.
Like WarioWare: Twisted!, a key gimmick of Yoshi Topsy-Turvy is that its cartridge contains a built-in gyroscope that detects if the game is being tilted. The difference is that Yoshi tilts in accordance to rotating the system.
== Story ==
Bowser and his armies were attacking Yoshi Island, causing chaos and disorder to the inhabitants. In response to this, a spirit named Hongo attempts to seal Bowser and his minions in his book named Forbidden Pop-Up Book to stop Bowser's destruction, but Hongo fails and accidentally seals the entire island in the book. Yoshi starts panicking, but a spirit named Spirit Who Loves Surprises explains to Yoshi that he must talk with Hongo and convince him to bring Yoshi Island back to normal, because spirits don't have enough power to defeat Bowser, who was hiding in a cave at the final chapter of the book, The Tale of Bowser's Cave. He also says that he was fired because he didn't know how to keep secrets. Yoshi gets mad, and as proof of his apology, the Spirit Who Loves Surprises gives to Yoshi the power to tilt the entire world and explains how to use it, but Yoshi accidentally hits the spirit with a boulder. Yoshi manages to convince Hongo to restore Yoshi Island under the conditions that Yoshi must defeat Bowser, because if he restores Yoshi Island with Bowser, he will attack Yoshi Island again. Now Yoshi must satisfy each one of the Yoshi Island Spirits. By doing this, he will receive Happiness Medals and the spirits will allow him to battle with Bowser.
Yoshi finds the Spirit of Cuteness, which explains to Yoshi that Bowser attacked Eggland and transformed every Eggling into apples. When Yoshi swallows an apple, it is revealed that the apple is really a Eggling. After completing four chapters and satisfying some spirits, Yoshi must complete a level where Bowser tries to attack him; it turns out that the Bowser is actually a fake one being controlled by the Spirit Who Loves Surprises. Yoshi gets mad, but the Spirit Who Love Surprises apologizes and says that he was just testing him to see if he is ready to battle with the real Bowser. After completing this level, Yoshi must complete two more chapters. When Yoshi has satisfied every spirit of Yoshi Island, he can battle with Bowser.
After completing the spirits' missions, rescuing the Egglings, and defeating Bowser, the spirits celebrate Yoshi's victory, and Hongo is very grateful for Yoshi's heroism. He makes a meal for Yoshi, but Yoshi still isn't happy. He then uses his magic to bring Yoshi's Island back to normal and Yoshi back to its original state. Yoshi eats the meal with the Egglings, who will never forget Yoshi's deeds. In the end, the Spirit Who Loves Surprises returns to work with Hongo.
== Gameplay ==
Yoshi Topsy-Turvy is a platform game in that the Game Boy Advance has to be tilted left or right to alter the gravity. There are only three levels of tilt: normal, left, and right. Fine-tuning of the level of tilt was not present. When the world is tilted, Yoshi can walk on walls, and many objects such as balls and enemies like Igashira-kuns roll downhill. The player can also make some objects go upside-down by continually changing the tilt direction.
To go to the next area, Yoshi must touch a ring made of stars. If Yoshi touches one, he cannot go back to the previous area because there is no ring to take him there. At the end of the level, Yoshi must touch a large star to win a Happiness Medal and go to the next level. Some areas require Yoshi to transform into a different form to collect items and reach the end of the level.
Depending on what level of the game players are at, the spirit who give the mission and the requirements for finishing the level change. Every level has a task given by one or two spirits, to increase the difficulty.
There is a Bonus Games mode, in which Shuffle Mode, Shuffle Mode EX, and other minigames can be played, as well as an Eggling Book. At the end of every level, there is a Bonus Chance!, which is a chance to play a Bonus Mission!. If Yoshi completes a Bonus Mission!, he wins 50 Coins.
Throughout the game, Yoshi will find various enemies which drain his health meter if he touches them. Yoshi can swallow hearts to restore one point of his health meter; a larger heart completely restores Yoshi's health meter. These enemies play important roles in the game; missions given by the Spirit of Power involve defeating a certain number of enemies, and missions given by the Spirit of Kindness involve not defeating enemies. Unlike in other Yoshi games, Yoshi produces a small puff of air after eating an enemy instead of making eggs.
If Yoshi completes the task given by the spirit, he wins a Happiness Medal. If Yoshi completes the level with a much better score than that required, he wins a Gold Medal.
