Those of you in the UK can now preorder the Mega Yarn Yoshi Amiibo from the Nintendo UK store. There are three different options, but unfortunately the standalone Amiibo (£34.99) has already sold out. Nevertheless, you can still get your hands on the £74.99 bundle, which includes a Mega Yarn Yoshi Amiibo, a copy of Yoshi's Woolly World, and a Yoshi Backpack. There is another bundle for £116.99 which includes all of the above, as well as three standard size Yarn Yoshi Amiibo in green, blue and pink.
If you haven't yet got a copy of Woolly World, then perhaps one of these bundles will make it an even better purchase!
