And now for something weird.
It's a ball-shaped modern Sonic plush keychain. But why a ball? Sonic already rolls up into a ball for spin attacks, so there's no need to strangely shape him into a ball with big body & tiny odd limbs...but that's just what happened here. It's like his head is combined with the body somehow & creates a rather impractical large sphere keychain.
Interestingly, this is by GE who will release it once their license is re-activated. It is the first such confirmed product from them after it was removed via Boom Ban. The item's photo was discovered in spring 2018, but the license for GE is set to return in 2019...which is likely when they will be able to release this (if they choose 'right away') Hopefully GE can re-debut with something more practical and appealing.
