Yoshi's Woolly World

Yoshi's Woolly World is a 2.5D side-scrolling game for the Wii U by Good-Feel. It is the fifth main platform game starring Yoshi and the first Yoshi home console game since Yoshi's Story. The game takes place in a handcrafted universe, similar to the one in Kirby's Epic Yarn, which was also developed by Good-Feel. It follows the adventure of the Yoshis trying to defeat the evil wizard Kamek, who unwove their friends and scattered their materials across six worlds. uIt was originally called Yarn Yoshi.

Like with most other Nintendo 3DS and Wii U software titles, this title can be purchased at retail stores or from the Nintendo eShop. The digital version requires 7991.8 MB (approx. 7.8 GB) of memory to be installed. Due to the software's size, standard set Wii U consoles cannot download it without an external storage device, but Deluxe Wii U consoles can.

A port of this game titled Poochy & Yoshi's Woolly World was released for Nintendo 3DS in 2017.

As of November 7, 2017, Nintendo has terminated the Miiverse service, which renders this game's Miiverse stamps unusable.

General
The game's story revolves around Craft Island, a paradise for the Yoshis. One day, Kamek turns all but two of the Yoshis into Wonder Wools as a favor to Baby Bowser, who wishes to use the accumulated yarn to construct a new castle in his name. When the remaining two Yoshis notice Kamek inadvertently dropping Wonder Wools around the areas next to Craft Island, they set out on a quest to collect them all and thus restore all of the unwoven Yoshis.

After Baby Bowser is defeated at his castle, Kamek uses his remaining Wonder Wools to make him more powerful. Despite this, Baby Bowser is defeated again, returning all of the remaining unwoven Yoshis back to normal. The Yoshis return to Craft Island, while Baby Bowser takes some time to "think about what he's done".

In-game
From the game's opening cinematic: Narrator: Welcome to Craft Island, a tiny place in the middle of the Handmade Ocean. Life here for the Yoshi clan is nothing but peaceful and leisurely. Or rather, it HAD been nothing but peaceful and leisurely, until... Kamek: "Hello, li'l Yoshis! Sorry to drop in so suddenly, but I need to turn you all into yarn! Thanks!" Kamek: "Eh, at this rate, I'll be here through lunch. C'mon, I'm busy! EVERYONE becomes yarn!" Kamek: "There. This should be plenty. Well, I'd better get back. Toodles!" Kamek: "EEEEEEEEK! That's quite enough! I've had it with you annoying Yoshis!" Narrator: There's still hope! As Kamek flies away, he drops a handful of yarn! A rather important Yoshi meeting is held... "What do we do to save the others?" "We need to get that yarn back!" "Hurry! After that naughty trickster!" And so another grand Yoshi adventure begins! Will they be able to knit their friends back together? Onwards, Yoshis!

Gameplay
Yoshi's Woolly World is a platform game with textile and fabric environment which plays similarly to Super Mario World 2: Yoshi's Island and Yoshi's New Island, with many features coming from these games. With their extensible tongue, Yoshis are able to abduct enemies into his mouth and either eat them or spit them out as projectiles; however, instead of turning them into Yoshi eggs as in earlier games, they turn them into yarn balls, which can be thrown just like eggs. They can also be thrown at objects such as platforms and Warp Pipes made of strings and needles in order to make them solid. Smiley Flowers and Winged Clouds return and coins are replaced by beads. Each level contains 20 Stamp Patches, which are hidden inside common-looking beads, similarly to the Red Coins found in Yoshi's Island games. Collecting a number of Stamp Patches grants the player a set of Stamps. The Health Meter system returns from Yoshi's Story. As the Yoshis are attacked by enemies, their Health Meter decreases and can be replenished with Hearts. Additionally, the life system from the Yoshi's Island games is changed; if a Yoshi loses all of the points to its Health Meter, they are simply booted back to either the beginning of the level or the last checkpoint they touched.

The game features two options for standard gameplay. The first is "Classic Mode", which is the standard gameplay similar to previous Yoshi platforming games. The second mode is "Mellow Mode". In this mode, Yoshi is Winged Yoshi and players can fly around freely, providing an easier experience. Players can switch between the two modes at any time via the pause menu.

Controls
The player may use a total of four different controllers to play the game: the Wii U GamePad, the Wii Remote held sideways, the Wii Classic Controller Pro, and the Wii U Pro Controller. Returning from the Yoshi's Island installments is the two control schemes: patient and hasty, with patient being the default control style. When throwing an egg, patient requires the player to push the egg throwing button again to throw the egg while hasty control schemes allow the Yoshi to throw an egg when the button is released. The Gyro control scheme, which takes advantage of Wii U gyro capabilities to line up the cursor rather than the cursor moving being automatic back and forth, returns from Yoshi's New Island, though it may only be used if the player has the Wii Remote selected as their controller, thus making it closer to its Wario Land: Shake It! counterpart.

There are two control styles, A and B. A is the default style used for the game and in the game manuals. All D-Pad actions can also be done with the left stick while ZL and ZR can be used instead of L and R.

Cooperative
In co-op mode, the players control two Yoshis, with player one playing as the Yoshi color seen on the save file and player two. A Yoshi is able to eat their partner and either swallow them to use them as a yarn ball or spit them out to destroy obstacles. However, when a Yoshi eats their partner, the Yoshi getting eaten loses all of their yarn balls. If one of the Yoshis goes too far off screen, it is placed into a flying Yoshi Egg and is transported to the other Yoshi, similarly to bubbles in the New Super Mario Bros. games. When one of the Yoshis goes down a Warp Pipe, the other one is transported with it simultaneously. A Yoshi is also able to jump onto another Yoshi to use it as a platform.

amiibo
The game makes use of amiibo, and a series of yarn-made Yoshi amiibo was released alongside the game. When a Yarn Yoshi amiibo is scanned, it will provide a Double Yoshi mode. Double Yoshi mode functions similarly to the Double Mario power-up from Super Mario 3D World, in that both Yoshis follow the single player's inputs, but with the additional functions of co-op mode. If the normal version of the Yoshi amiibo is scanned instead, a normal Yoshi copy will appear. Any Yoshi amiibo scanned will also unlock them for the amiibo tent upon completing the level.

In addition to the yarn amiibo, every Mario-related amiibo except for Princess Daisy, Waluigi and Boo, every Super Smash Bros. series amiibo except Pokémon and DLC characters, and the Inkling amiibo from the Splatoon series will unlock a pattern based on the character. Any other amiibo unlocks a green Yarn Yoshi wearing an amiibo shirt. Incidentally, this and the 3DS remake are the only games where both R.O.B amiibos have a different function, being that they unlock different patterns.

Additional playable characters
Many additional playable Yoshi designs can be unlocked by collecting Wonder Wool in the levels or by scanning different amiibo into the game.

During levels, the playable character Yoshi started out being made only of some yarn threads in his shape—however, using his tongue, the player could swallow Shy Guys to turn Yoshi into a three-dimensional, amigurumi crochet form.

Trivia

 * Although Yoshi's Woolly World was released in 2015, the 2014 game Super Smash Bros. for Wii U included a stage based upon this game titled Woolly World. On a Miiverse post before the shutdown, it was stated that the stage was put in late in development.
 * This is the only game in the Yoshi series to be released in Europe before anywhere else in the world.
