Sunny Eggy is the most amazing Facebook sticker set

I was chatting to Kristie on Facebook Messenger when she sent me the following sticker:

Spa eggy

I spent a while looking at it, and I just couldn't figure out what it was supposed to be, until she explained that it was an egg in a face mask, and introduced me to the wonderful world of Sunny Eggy.

Facebook stickers are a strange concept to begin with, but the Sunny Eggy sticker set is especially strange. Every sticker is of an egg. Not an egg in a shell, but the yolk and white of an egg, with a little face and arms and legs.

Some eggys are happy:

Some are industrious and hard working:

Some are... unusual:

This eggy in particular is tripping and its face is falling off:

The more I look through the Sunny Eggy images the more I feel like I am just scratching the surface. I tried to find out where these stickers came from – Facebook lists the author of the stickers as "Kangaroo" but various searches for combinations of the words "Sunny", "Eggy" and "Kangaroo" have not lead to any useful information so far.

The images use a lot of manga iconography, like the little angry cruciform, that makes me suspect that the stickers are Japanese in origin, but that's not a lot to go on.

I want to understand the secrets of Sunny Eggy. If you have any information that might help, then tweet me @baxt3r.

Until then I'll be trying to fathom the origins of these little eggy creatures.
