Yoshi's Woolly World

Yoshi's Woolly World (originally called Yarn Yoshi) is a 2.5D side-scrolling game for the Wii U by Good-Feel. It's the first Yoshi home console game since Yoshi's Story (which was originally released in 1997). The game uses similar art material of yarn and textiles from the aforementioned game and Wii game from the Kirby franchise, Kirby's Epic Yarn, which was also developed by Good-Feel.

Story
The game takes place in Craft Island. Kamek turns the Yarn Yoshis into Wonder Wool, but misses two of them, who have to save the rest.

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 Story, with many features coming from these games. Yoshi is able to eat enemies but, instead of turning them into Yoshi Eggs as in earlier games, he now turns them into yarn balls, that 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" 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 hit point system comes back from Yoshi's Story. As the Yoshis are attacked by enemies, their Health Meter decreases and can be replenished with Hearts.

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.

In co-op mode, the players control two Yoshis, Green Yoshi and Red Yoshi. 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 transported to the other Yoshi. When one of the Yoshis goes down a Warp Pipe the other one is transported with it simultaneously. A Yoshi is able to jump onto another Yoshi and use it as a platform.

amiibo
The game makes use of amiibo, and a series of yarn made Yoshi amiibo 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. Instead, if the normal version of the Yoshi amiibo is scanned, a normal Yoshi copy will appear.

All of the other amiibo (except the Pokémon ones) are compatible with the game and will unlock a pattern based on the character.
